2-Anilino-5-nitrobenzenesulfonic acid is an aromatic sulfonic acid compound with the molecular formula CHNOS and a molecular weight of approximately 294.29 g/mol. The molecule consists of two benzene rings connected via an anilino (-NH-) linkage. One of the rings carries a nitro group (-NO) at the para position and a sulfonic acid group (-SOH) at the meta position relative to the amino linkage. This structural arrangement gives the compound excellent reactivity for electrophilic substitution and diazo coupling, making it a valuable intermediate in the synthesis of azo dyes, especially those used in textiles and paper industries. It typically appears as a yellowish to brown powder and is soluble in water, particularly in alkaline conditions. While industrially useful, the compound may pose health hazards such as skin or eye irritation and should be handled with proper protective equipment and stored in a cool, dry, well-ventilated area.

4-Aminodiphenylamine-2-sulfonic acid is an organic compound with the molecular formula CHNOS and a molecular weight of 264.30 g/mol. Structurally, it consists of two aromatic rings connected by an amine (-NH-) bridge, with one ring substituted by an amino group (-NH) at the para position and a sulfonic acid group (-SOH) at the ortho position. This compound typically appears as a brownish or off-white crystalline powder and is soluble in water, especially under alkaline conditions. It plays a significant role as an intermediate in the manufacture of azo dyes, where it acts as a coupling component due to the reactivity of its amino and sulfonic acid groups. These characteristics make it especially useful in the textile and pigment industries. While it is an important chemical in dye synthesis, proper handling is essential as it may cause irritation to the skin, eyes, and respiratory system. It should be stored in a cool, dry place and used with appropriate protective equipmen

4-Nitro-2-chlorobenzenesulfonic acid, commonly known as Para-Nitro-Chlorobenzene Ortho-Sulfonic Acid, is an aromatic sulfonic acid derivative with the molecular formula CHClNOS and a molecular weight of 237.61 g/mol. It features a benzene ring substituted with a nitro group at the para position, a chlorine atom at the ortho position, and a sulfonic acid group also at the ortho position. This compound typically appears as a yellowish to brown crystalline solid and is moderately soluble in water and alkaline solutions. It is primarily used as an intermediate in the production of dyes, especially reactive dyes, due to its sulfonic acid group which enhances solubility and chemical reactivity. Additionally, it finds application in the manufacture of pigments and specialty chemicals. Care must be taken in handling, as it may cause irritation upon contact with skin, eyes, or if inhaled, and should be stored in a cool, dry place away from incompatible substances.
