Chemical Structure

5-Bromo-2-(methylthio)benzo[d]oxazole CAS 372136-69-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 244.11 g/mol gives 5-Bromo-2-(methylthio)benzo[d]oxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Bromo-2-(methylthio)benzo[d]oxazole (CAS 372136-69-1), a certified reference material (molecular formula C8H6BrNOS, MW 244.11 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 5-Bromo-2-(methylthio)benzo[d]oxazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 5-Bromo-2-(methylthio)benzo[d]oxazole 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.
