Product Overview

• 4-Amino-6-Chloro-1,3-Benzenedisulphonamide, widely known across international active ingredient synthesis pipelines by its synonym Salamide, is a highly essential chlorinated aromatic disulfonamide compound structure. It serves as a vital structural core key intermediate in chemical synthesis channels for high-efficiency renal therapeutics. Commercially supplied as a fine, white to cream-colored crystalline powder, it delivers consistent melting thresholds and highly predictable reactivity metrics. ProCorBay International distributes premium-grade Salamide building blocks to large pharmaceutical active ingredient processing facilities and advanced chemical synthesis laboratories globally.
• This compound is typically manufactured via the targeted chlorosulfonation of high-purity 3-chloroaniline substrates using excess chlorosulfonic acid loops under strict chemical pressure profiles, followed by cold amidation using aqueous ammonia pools, acid precipitation, and water washings. ProCorBay manages strategic distribution lanes with premier halogenated organosulfur complexes to deliver batches featuring very low level of structural analogue impurities, minimal free chloride levels, and high active chemical assays.
• Within life sciences manufacturing, this disulfonamide building block acts as an indispensable regulatory key starting material. It functions as the direct predecessor for synthesizing major thiazide class diuretic agents—most notably serving as the key synthetic block for compounding Hydrochlorothiazide (HCTZ) and Chlorothiazide. The presence of the two distinct sulfonamide forks adjacent to the chlorine atom on the benzene core allows formulators to easily run single-carbon ring-closure reactions using formaldehyde or formic acid variants. ProCorBay handles deep, multi-ton inventory lines to ensure commercial pricing safety and reliable supply continuity for generic drug lines.
