Chemical Structure

5-(Hydroxymethyl)benzo[c][1,2]oxaborol-1(3H)-ol CAS 905710-77-2 chemical structure

Description

The occurrence of 5-(Hydroxymethyl)benzo[c][1,2]oxaborol-1(3H)-ol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(Hydroxymethyl)benzo[c][1,2]oxaborol-1(3H)-ol (CAS 905710-77-2), molecular formula C8H9BO3 and molecular weight 163.97 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 5-(Hydroxymethyl)benzo[c][1,2]oxaborol-1(3H)-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 163.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 5-(Hydroxymethyl)benzo[c][1,2]oxaborol-1(3H)-ol 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.
