N-(4-bromophenyl)-3-chloro-6-methylbenzo[b]thiophene-2-carboxamide CAS 332381-91-6

Description

N-(4-bromophenyl)-3-chloro-6-methylbenzo[b]thiophene-2-carboxamide (CAS 332381-91-6), molecular formula C16H11BrClNOS and molecular weight 380.69 g/mol, is a CATO reference standard with documented purity and traceability.

N-(4-bromophenyl)-3-chloro-6-methylbenzo[b]thiophene-2-carboxamide (C16H11BrClNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
