The chemical structure of the compound of N- (2-cyanoethyl) guanidine and N '-2-ethoxyacetic acid is as follows:
In this compound, the N- (2-cyanoethyl) guanidine part, in the cyanoethyl group, the cyano group (-CN) is a functional group containing carbon and nitrogen three bonds, which has high polarity and reactivity. The cyano group is connected to one end of the ethyl group, and the ethyl group is used as the connecting chain, and the other end is connected to the guanidine group. The guanidine group is a strong basic group containing nitrogen and has resonance stability. The lone pair of electrons on its nitrogen atom makes the guanidine group easy to accept protons and is basic.
And the N '-2-ethoxy acetic acid part, the ethoxy group (-OCH -2 CH 😉) is connected to the carboxyl α-carbon atom of the acetic acid. The ethoxy group is the power supply group, which will affect the electron cloud distribution of the carboxyl group. The carboxyl group (-COOH) is acidic and can undergo common carboxyl reactions such as acid-base reactions and esterification reactions.

The spatial arrangement and electronic effects of the overall structure will determine the performance of the compound in different chemical reactions and application scenarios, such as in organic synthesis, or because of its functional groups, it becomes an important intermediate, participating in various bonding and breaking reactions, exhibiting unique chemical behaviors.

N- (2-hydroxyethyl) guanidine and N '- 2-ethoxyacetic acid are very important in biological experiments.
N- (2-hydroxyethyl) guanidine plays a significant role in the field of protein research. First, it can be used as a protein denaturant. In many protein structure and function exploration experiments, in order to clarify the relationship between the natural conformation and function of proteins, its structure often needs to be changed. N- (2-hydroxyethyl) guanidine can denature the protein by destroying the hydrogen bonds and hydrophobic interactions in the protein molecule, and transform the protein from the natural state to the stretched state, which helps researchers to deeply analyze the influence of protein structure changes on its function. Second, it also has important uses in protein crystallization experiments. Protein crystallization is a key step in determining its three-dimensional structure, and N- (2-hydroxyethyl) guanidine can adjust the physical and chemical properties of the solution, such as ionic strength, pH, etc., promote the orderly arrangement of protein molecules, and improve the success rate of protein crystallization.
Furthermore, N '-2-ethoxyacetic acid is very useful in cell culture experiments. Cell culture is a commonly used method for biological experiments, and N '-2-ethoxyacetic acid can be used as a supplementary component of cell culture medium. It can provide necessary nutrients and a suitable environment for cell growth, and affect the metabolic pathway of cells. For example, it can participate in the synthesis process of some biological macromolecules in cells, promote cell proliferation and differentiation, and maintain normal physiological functions of cells. It is indispensable in experiments to study cell growth, development, differentiation and disease mechanisms. At the same time, N' -2-ethoxyacetic acid can be used as a regulator of enzymes in experiments on enzyme activity. The activity of some enzymes is affected by specific small molecule compounds in the reaction system. N '2-ethoxyacetic acid can bind to specific parts of the enzyme molecule, change the conformation of the enzyme molecule, and then regulate the activity of the enzyme, which helps researchers to explore the mechanism of action and kinetic properties of the enzyme.

In order to know the pH buffer range of N - (2 -methylamino) pyridine - N '- 2 -ethoxybenzoic acid, it is necessary to know the chemistry of the two. They have acid-base properties and can interact with protons in solution to form a buffer system. The buffer range is related to the dissociation constant of the buffer pair ($K_a $). According to the Henderson-Hasselbach equation ($pH = pK_a\ pm 1 $), the effective buffer range of the buffer system is about 1 unit of the $pK_a $value of its conjugated acid.
However, if you want to know the buffer range of the buffer system composed of this particular compound, you need to know its specific $pK_a $value. Because there is no relevant $pK_a $data, it is difficult to accurately give the pH buffer range.
can usually be measured experimentally, such as potentiometric titration, acid-base titration of the compound, pH change, according to the titration curve to obtain $pK_a $, and then obtain the buffer range. Or check chemical literature, databases, find the $pK_a $information of the compound or similar structures to deduce its buffer range. If there is no exact $pK_a $, only according to the buffering characteristics of common organic acids and bases, the buffering range of such nitrogenous and carboxyl compounds may be between pH 4-8, but this is only speculation and needs to be determined by experiments or exact data.

To prepare a solution of N- (2-cyanoethyl) guanidine and N '-2-ethoxyacetic acid, the following method is required.
Prepare the required drugs and utensils first to ensure that the drugs are pure and free of impurities, and the utensils are clean and dry. In a well-ventilated environment, measure the reactants in accurate proportions. For N- (2-cyanoethyl) guanidine and N' -2-ethoxyacetic acid, the ratio is determined according to the stoichiometric relationship of the reaction and the degree of reaction to be achieved.
Measure an appropriate amount of solvent, such as ethanol, water or specific mixed solvents. The choice of solvent is related to the solubility of the reactants and the process of the reaction. Pour the solvent into a clean reaction vessel, such as a round bottom flask.
Then, slowly add N- (2-cyanoethyl) guanidine, and gently stir with a glass rod or a magnetic stirrer to promote uniform dispersion in the solvent. Next, add N '-2-ethoxyacetic acid in sequence. When adding, do not be too hasty to avoid the reaction getting out of control.
During the stirring process, pay close attention to the temperature change of the solution. If the reaction is exothermic, cooling measures can be taken in a timely manner, such as cooling in a cold water bath, to prevent the decomposition of the reactants or side reactions caused by excessive temperature; if it is an endothermic reaction, moderate heating is required to maintain the appropriate temperature of the reaction.
Continuous stirring allows the reactants to fully contact and react. During this process, the color state of the solution may change, which is a sign of the reaction going on. After a certain period of time, when the reaction reaches the expected level, the solution is made.
The solution made should be properly stored. Or according to the subsequent use, decide whether further treatment is required, such as filtration to remove impurities, concentration or dilution. Throughout the operation, be sure to strictly follow safety procedures and avoid direct contact with the reactants and solutions to prevent damage.
