This is about whether C.I. Acid Red 118 (6E) - 5- (2 - {3 - [ethyl (phenyl) sulfamic acid] - 4 - methylphenyl} hydrazine) - 6 - imino - 4 - oxo - 4,6 - dihydronaphthalene - 2 - sulfonic acid is toxic. This compound is an organic synthesis product and is often used in the field of dyes.
Looking back at the past, in books such as Tiangong Kaiwu, although this specific compound is not mentioned, the ancients also had insights on the use of dyes and the cognition of poisons. At that time, the dyes used were mostly natural, and the distinction of toxicity was based on experience and observation. For example, some vegetable dyes, after long-term use, it is known that they are non-toxic and harmless, and can be used for fabric dyeing.
Today is different from the past, modern chemical analysis technology can accurately measure the toxicity of compounds. For this C.I. Acid Red 118, professional toxicological tests are required to observe its impact on biological cells and tissues, such as whether it is mutagenic, teratogenic, carcinogenic, etc. Although there is no conclusive ancient evidence to determine its toxicity, according to the modern chemical research process and rigorous experiments, it can be determined whether it is toxic or not, and it cannot be rashly concluded.
C.I.Acid Red 118 (6E) -5- (2- {3- [Ethyl (Phenyl) Sulfamoyl] -4-Methylphenyl} Hydrazino) -6-Imino-4-Oxo-4, what are the physical properties of 6-Dihydronaphthalene-2-Sulfonic Acid

Looking at its morphology, at room temperature, or as a powder-like solid, the color is mostly bright red, which is consistent with its essence as an acid dye. Bright color is a significant feature of its appearance.
When it comes to solubility, because of its sulfonic acid groups, it exhibits a certain solubility in water and can form a uniform solution. This property is crucial in the application of dyes, ensuring that they are uniformly dispersed in the dye solution, thereby making the dyeing more uniform.
As for the melting point, although no exact records have been found, it is speculated that its melting point may be in a certain range according to its molecular structure and the generality of similar compounds. Due to the interaction of many conjugate systems and hydrogen bonds in the molecule, the intermolecular force is enhanced, so the melting point is not extremely low.
In terms of density, it is also difficult to have accurate values due to limited data. However, according to common sense, its density is similar to that of common organic compounds, which is related to the composition and accumulation of molecules.
In addition, the stability of this substance is also a consideration of physical properties. Under general environmental conditions, without the influence of extreme factors such as strong acids, strong bases or strong oxidants, its structure can remain relatively stable, which is the basis for its performance during storage and use.
Overall, the physical properties of this substance are interrelated and play a decisive role in its application in the dye industry. From dissolution and dispersion to dyeing effect, it is closely related.
