Chemical Structure

Malic Acid Impurity 10 CAS 1800467-68-8 chemical structure

Description

As a certified reference material (CRM), Malic Acid Impurity 10 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.

Malic Acid Impurity 10 (CAS 1800467-68-8) is a certified pharmaceutical impurity reference standard with the molecular formula C8H10O9 and a molecular weight of 250.16 g/mol.

Owing to a carbohydrate-derived structure, Malic Acid Impurity 10 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
