Chemical Structure

Pentoxifylline Impurity 19 CAS 6135-54-2 chemical structure

Description

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.

Pentoxifylline Impurity 19 (CAS 6135-54-2) is a certified pharmaceutical impurity reference standard with the molecular formula C8H16O2 and a molecular weight of 144.21 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Pentoxifylline Impurity 19 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

As a certified reference material (CRM), Pentoxifylline Impurity 19 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.
