Chemical Structure

4-Bromobenzo[b]thiophene-5-carbaldehyde CAS 131124-29-3 chemical structure

Description

The occurrence of 4-Bromobenzo[b]thiophene-5-carbaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Bromobenzo[b]thiophene-5-carbaldehyde (CAS 131124-29-3), molecular formula C9H5BrOS and molecular weight 241.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Bromobenzo[b]thiophene-5-carbaldehyde (C9H5BrOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.

As a certified reference material (CRM), 4-Bromobenzo[b]thiophene-5-carbaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
