Chemical Structure
Description
The occurrence of 2-Bromo-5-((tert-butoxycarbonyl)amino)thiazole-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-5-((tert-butoxycarbonyl)amino)thiazole-4-carboxylic acid (CAS 1312697-86-1) is a high-purity analytical reference standard with the molecular formula C9H11BrN2O4S and a molecular weight of 323.16 g/mol.
Structurally, 2-Bromo-5-((tert-butoxycarbonyl)amino)thiazole-4-carboxylic acid (C9H11BrN2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 323.16 g/mol, it falls into the moderately-high-molecular-weight range. 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), 2-Bromo-5-((tert-butoxycarbonyl)amino)thiazole-4-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.
