4-Bromoisothiazole-3-carboxylic Acid CAS 4576-88-9

Description

The occurrence of 4-Bromoisothiazole-3-carboxylic Acid is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Bromoisothiazole-3-carboxylic Acid (CAS 4576-88-9), molecular formula C4H2BrNO2S and molecular weight 208.03 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H2BrNO2S, 4-Bromoisothiazole-3-carboxylic Acid contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4-Bromoisothiazole-3-carboxylic Acid 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.
