For professionals in the chemical industry, a thorough understanding of the chemical properties of raw materials is fundamental to successful product development and manufacturing. 2-Amino-4-chlorophenol-6-sulfonic Acid, bearing the CAS number 88-23-3, is a prominent example of a fine chemical intermediate whose properties dictate its utility, particularly in the realm of dye synthesis. Its molecular structure, a substituted benzene ring with amino, hydroxyl, chloro, and sulfonic acid groups, imparts specific reactivity and characteristics.

The molecular formula for 2-Amino-4-chlorophenol-6-sulfonic Acid is C6H6ClNO4S, with a molecular weight of approximately 223.63 g/mol. Typically, it presents as an off-white solid. This physical state is common for many organic compounds of similar molecular weight and functionalization, and it influences handling, storage, and formulation procedures. The presence of the sulfonic acid group (-SO3H) renders the molecule acidic and generally increases its water solubility compared to non-sulfonated analogs, although precise solubility data might vary depending on conditions like pH and temperature.

The reactivity of 2-Amino-4-chlorophenol-6-sulfonic Acid is attributed to its multiple functional groups. The amino group (-NH2) can undergo diazotization, a critical step in the synthesis of azo dyes. The phenolic hydroxyl group (-OH) can participate in various reactions, and the chloro substituent (-Cl) and sulfonic acid group influence the electronic distribution and reactivity of the aromatic ring. These features are precisely what make it an effective intermediate for the synthesis of specific dyes like Diamond Black P 2 B and acid chrome blue dyes. Manufacturers rely on these predictable chemical properties to achieve the desired dye characteristics.

When you buy 2-Amino-4-chlorophenol-6-sulfonic acid online, reviewing the Certificate of Analysis (CoA) is essential. This document will detail key chemical properties such as purity (often specified as >99% by HPLC), appearance, melting point (if determined), and spectral data that confirm its identity. Understanding these CAS 88-23-3 chemical properties allows formulators to accurately predict its behavior in reaction mixtures and ensure it meets the stringent requirements for producing consistent dye products.
