Chemical Structure

Malic Acid Impurity 15 CAS 71901-42-3 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.

As a process- or degradation-related impurity, Malic Acid Impurity 15 (CAS 71901-42-3, C6H10O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a carbohydrate-derived structure, Malic Acid Impurity 15 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

As a certified reference material (CRM), Malic Acid Impurity 15 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.
