2-[5-[2-cyano-3-(dimethylamino)prop-2-enoyl]-3,4-dimethyl-thieno[2,3-b]thiophene-2-carbonyl]-3-(dimethylamino)prop-2-enenitrile CAS 1191035-73-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[5-[2-cyano-3-(dimethylamino)prop-2-enoyl]-3,4-dimethyl-thieno[2,3-b]thiophene-2-carbonyl]-3-(dimethylamino)prop-2-enenitrile.

2-[5-[2-cyano-3-(dimethylamino)prop-2-enoyl]-3,4-dimethyl-thieno[2,3-b]thiophene-2-carbonyl]-3-(dimethylamino)prop-2-enenitrile (CAS 1191035-73-0) is a high-purity analytical reference standard with the molecular formula C20H20N4O2S2 and a molecular weight of 412.53 g/mol.

The molecular framework of 2-[5-[2-cyano-3-(dimethylamino)prop-2-enoyl]-3,4-dimethyl-thieno[2,3-b]thiophene-2-carbonyl]-3-(dimethylamino)prop-2-enenitrile (C20H20N4O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-[5-[2-cyano-3-(dimethylamino)prop-2-enoyl]-3,4-dimethyl-thieno[2,3-b]thiophene-2-carbonyl]-3-(dimethylamino)prop-2-enenitrile 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.
