Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-(2,5-Dioxopyrrolidin-1-yl)benzamido)-6-ethyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride.
CATO supplies 2-(3-(2,5-Dioxopyrrolidin-1-yl)benzamido)-6-ethyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (CAS 1216557-45-7), a certified reference material (molecular formula C21H22N4O4SHCl, MW 462.95 g/mol) for analytical method development and quality control.
Structurally, 2-(3-(2,5-Dioxopyrrolidin-1-yl)benzamido)-6-ethyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (C21H22N4O4SHCl) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 462.95 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.
CATO manufactures 2-(3-(2,5-Dioxopyrrolidin-1-yl)benzamido)-6-ethyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride 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.
