Chemical Structure
Description
3-(4-bromobenzoyl)-4H,5H,6H-cyclopenta[b]thiophen-2-amine (CAS 223423-37-8), molecular formula C14H12BrNOS and molecular weight 322.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-bromobenzoyl)-4H,5H,6H-cyclopenta[b]thiophen-2-amine (C14H12BrNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. 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 3-(4-bromobenzoyl)-4H,5H,6H-cyclopenta[b]thiophen-2-amine 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.
