Ethyl 2-amino-7-bromo-1,3-benzoxazole-5-carboxylate CAS 1820687-34-0 chemical structure

Description

The occurrence of Ethyl 2-amino-7-bromo-1,3-benzoxazole-5-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 2-amino-7-bromo-1,3-benzoxazole-5-carboxylate (CAS 1820687-34-0) is a high-purity analytical reference standard with the molecular formula C10H9BrN2O3 and a molecular weight of 285.09 g/mol.

Based on its molecular formula C10H9BrN2O3, Ethyl 2-amino-7-bromo-1,3-benzoxazole-5-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
