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 N,N'-(1,3-Phenylenebis(methylene))bis(thiophene-2-carboxamide).
N,N'-(1,3-Phenylenebis(methylene))bis(thiophene-2-carboxamide) (CAS 331987-72-5), molecular formula C18H16N2O2S2 and molecular weight 356.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N,N'-(1,3-Phenylenebis(methylene))bis(thiophene-2-carboxamide) (C18H16N2O2S2) 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 its high hydrophobicity (logP), 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).
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 N,N'-(1,3-Phenylenebis(methylene))bis(thiophene-2-carboxamide) 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.
