Ethyl 5-mercapto-2-thioxo-1,3-dithiole-4-carboxylate CAS 400083-77-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 5-mercapto-2-thioxo-1,3-dithiole-4-carboxylate.

CATO supplies Ethyl 5-mercapto-2-thioxo-1,3-dithiole-4-carboxylate (CAS 400083-77-4), a certified reference material (molecular formula C6H6O2S4, MW 238.37 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Ethyl 5-mercapto-2-thioxo-1,3-dithiole-4-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Ethyl 5-mercapto-2-thioxo-1,3-dithiole-4-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
