Chemical Structure

Dexpanthenol impurity 31 CAS 1112-32-9（free base） chemical structure

Description

The occurrence of Dexpanthenol impurity 31 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dexpanthenol impurity 31 (CAS 1112-32-9（free base）) is a certified pharmaceutical impurity reference standard with the molecular formula C6H11O4Na and a molecular weight of 170.14 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Dexpanthenol impurity 31 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Dexpanthenol impurity 31 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.
