Description

The occurrence of (2-Phenylbenzo[d]oxazol-5-yl)boronic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2-Phenylbenzo[d]oxazol-5-yl)boronic acid (CAS 866332-17-4), molecular formula C13H10BNO3 and molecular weight 239.03 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2-Phenylbenzo[d]oxazol-5-yl)boronic acid (C13H10BNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 239.03 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
