Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-chloro-2-methylphenyl)-8-methyl-4H-thieno[3,2-c]thiochromene-2-carboxamide.
CATO supplies N-(4-chloro-2-methylphenyl)-8-methyl-4H-thieno[3,2-c]thiochromene-2-carboxamide (CAS 477887-23-3), a certified reference material (molecular formula C20H16ClNOS2, MW 385.93 g/mol) for analytical method development and quality control.
Structurally, N-(4-chloro-2-methylphenyl)-8-methyl-4H-thieno[3,2-c]thiochromene-2-carboxamide (C20H16ClNOS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 385.93 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), N-(4-chloro-2-methylphenyl)-8-methyl-4H-thieno[3,2-c]thiochromene-2-carboxamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
