Chemical Structure
Description
The occurrence of 5-Bromothiazole-2-carbaldehyde, 97% is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromothiazole-2-carbaldehyde, 97% (CAS 933752-44-4) is a high-purity analytical reference standard with the molecular formula C4H2BrNOS and a molecular weight of 192.03 g/mol.
The molecular framework of 5-Bromothiazole-2-carbaldehyde, 97% (C4H2BrNOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-Bromothiazole-2-carbaldehyde, 97% 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.
