Chemical Structure

Tripropyl borate CAS 688-71-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tripropyl borate.

Tripropyl borate (CAS 688-71-1) is a high-purity analytical reference standard with the molecular formula C9H21BO3 and a molecular weight of 188.07 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Tripropyl borate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.07 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), Tripropyl borate 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.
