2,7-Dihydroxybenzo[d][1,3,2]dioxaborole-5-carboxylic acid CAS 78456-98-1

Description

The occurrence of 2,7-Dihydroxybenzo[d][1,3,2]dioxaborole-5-carboxylic acid is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,7-Dihydroxybenzo[d][1,3,2]dioxaborole-5-carboxylic acid (CAS 78456-98-1), molecular formula C7H5BO6 and molecular weight 195.92 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,7-Dihydroxybenzo[d][1,3,2]dioxaborole-5-carboxylic acid (C7H5BO6) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 195.92 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).

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.
