5-Bromo-N-(4,7-dimethylbenzo[d]thiazol-2-yl)thiophene-2-carboxamide CAS 905692-99-1

Description

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.

5-Bromo-N-(4,7-dimethylbenzo[d]thiazol-2-yl)thiophene-2-carboxamide (CAS 905692-99-1), molecular formula C14H11BrN2OS2 and molecular weight 367.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-N-(4,7-dimethylbenzo[d]thiazol-2-yl)thiophene-2-carboxamide (C14H11BrN2OS2) 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
