Acetylcysteine Impurity 50 CAS 24125-26-6

Description

Compared with other compounds in its class, the molecular weight of 286.37 g/mol gives Acetylcysteine Impurity 50 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Acetylcysteine Impurity 50 (CAS 24125-26-6), a pharmacopoeial impurity reference standard (molecular formula C14H26N2O4, MW 286.37 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Acetylcysteine Impurity 50 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Acetylcysteine Impurity 50 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.
