Chemical Structure
Description
The occurrence of (2-(Methoxycarbonyl)thiazol-5-yl)boronic acid is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2-(Methoxycarbonyl)thiazol-5-yl)boronic acid (CAS 2256708-88-8), molecular formula C5H6BNO4S and molecular weight 186.98 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2-(Methoxycarbonyl)thiazol-5-yl)boronic acid (C5H6BNO4S) contains a carbohydrate-derived structure, an amide group, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 186.98 g/mol, it falls into the medium-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
