Chemical Structure

Pentoxifylline Impurity 20 CAS 2035-08-7 chemical structure

Description

As a process- or degradation-related impurity, Pentoxifylline Impurity 20 (CAS 2035-08-7, C8H16O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Pentoxifylline Impurity 20 (C8H16O2) contains a carboxylic acid group, 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.

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), Pentoxifylline Impurity 20 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.
