Etamsylate

Synonyms: 2,5-Dihydroxybenzenesulfonic acid diethylamine salt, Diethylammonium 2,5-dihydroxybenzenesulfonate, Etamsylate, Ethamsylate, 2624-44-4

Etamsylate is a synthetic small-molecule API supplied as a white to off-white crystalline powder. It is the diethylamine salt of 2,5-dihydroxybenzenesulfonic acid and is manufactured under GMP conditions for pharmaceutical formulation.

Material is offered at ≥99.0% assay by HPLC, with typical water content controlled to ≤0.5%. It dissolves readily in water and polar solvents, making it suitable for aqueous processing.

Formulators use etamsylate in tablet and capsule products, and in injectable solutions where a water-soluble hemostatic agent is required. It also finds use in oral liquid and powder blends for clinical nutrition and specialty pharma.

Applications & Formulation Use

Etamsylate is formulated into immediate-release tablets and hard-shell capsules, often in combination with other hemostatic agents. In liquid formats, it is incorporated into oral solutions and injectables, where its aqueous solubility simplifies processing. It is also used in powder blends for sachets and in topical gel preparations for localized application.

The compound is compatible with common excipients such as microcrystalline cellulose, lactose, and magnesium stearate. Its stability in aqueous solution supports use in sterile injectables, although terminal sterilization may require pH adjustment.

Sourcing & Production

Etamsylate is produced via a multi-step synthesis starting from hydroquinone, involving sulfonation and subsequent salt formation with diethylamine. The process is carried out in cGMP-compliant facilities in China and Europe, with strict control on residual solvents and heavy metals. Final crystallization yields a consistent crystalline powder that meets pharmacopeial standards.

Each batch is manufactured under an ISO 9001 quality system and is accompanied by a certificate of analysis. Material is supplied in polyethylene-lined fiber drums or as custom-packed quantities to suit development and production needs.
