Sulphanilic Acid-Lancer

Sulphanilic Acid by Lancer is a premium-grade laboratory chemical with a wide range of industrial, academic, and research applications. Known chemically as 4-aminobenzenesulfonic acid, Sulphanilic Acid is a white to off-white crystalline powder composed of an amine group and a sulfonic acid group attached to a benzene ring. With the molecular formula C6H7NO3S and a molecular weight of approximately 173.19 g/mol, this compound is widely recognized for its role as a diazotizable aromatic amine and an essential intermediate in dye, pigment, and pharmaceutical manufacturing.

One of the most prominent applications of Sulphanilic Acid is in the production of azo dyes. It is a primary component used in diazotization reactions, where it reacts with nitrous acid to form diazonium salts. These salts further react with coupling agents to yield vivid and stable azo dyes used in the textile, paper, ink, and food coloring industries. The sulfonic acid group in Sulphanilic Acid imparts water solubility, allowing for better dispersion and application in aqueous dye formulations.

In analytical chemistry, Sulphanilic Acid plays a critical role as a reagent in the Griess test, which is used for detecting nitrites in water and biological samples. When paired with N-(1-naphthyl)ethylenediamine dihydrochloride, Sulphanilic Acid forms a sensitive diazotization reagent that yields a pink to reddish azo dye in the presence of nitrites. This test is essential for environmental monitoring, wastewater analysis, and health diagnostics.

Lancer’s Sulphanilic Acid is produced under strict quality-controlled conditions, ensuring high chemical purity, minimal contamination, and consistent batch quality. This makes it highly suitable for use in research laboratories, chemical synthesis processes, and industrial manufacturing. Each batch is analyzed for parameters such as melting point, moisture content, and solubility to ensure conformity with international laboratory standards.

In the pharmaceutical sector, Sulphanilic Acid is used as an intermediate in the synthesis of sulfa drugs—compounds that were among the first antibiotics used in modern medicine. Even today, its derivatives continue to play a role in antimicrobial research, as well as in the synthesis of pharmaceutical ingredients and excipients.

Sulphanilic Acid is also utilized in electroplating and corrosion inhibition. Its ability to interact with metal ions and create protective layers makes it valuable in metal treatment processes. Moreover, it is employed in food analysis techniques and protein determination experiments such as the ninhydrin reaction.
