Chemical Structure

Oxybispropanol dibenzoate CAS 27138-31-4 chemical structure

Description

As a certified reference material (CRM), Oxybispropanol dibenzoate 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.

Oxybispropanol dibenzoate (CAS 27138-31-4) is a high-purity analytical reference standard with the molecular formula C20H22O5 and a molecular weight of 342.39 g/mol.

Oxybispropanol dibenzoate (C20H22O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
