Boric Acid CAS 10043-35-3 chemical structure

Description

Boric Acid (CAS 10043-35-3) is a high-purity analytical reference standard with the molecular formula H3BO3 and a molecular weight of 61.83 g/mol.

Owing to an inorganic composition, Boric Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 61.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), Boric 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.
