Chemical Structure

2-Bromooxazole-4-carboxamide CAS 941306-42-9 chemical structure

Description

The occurrence of 2-Bromooxazole-4-carboxamide is closely related to an amide 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.

CATO supplies 2-Bromooxazole-4-carboxamide (CAS 941306-42-9), a certified reference material (molecular formula C4H3BrN2O2, MW 190.98 g/mol) for analytical method development and quality control.

Based on its molecular formula C4H3BrN2O2, 2-Bromooxazole-4-carboxamide contains an amide 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 190.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
