Chemical Structure
Description
Trimetazidine impurity 31 is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
CATO supplies Trimetazidine impurity 31 (CAS CATO-C4X-180331), a pharmacopoeial impurity reference standard (molecular formula N/A, MW N/A g/mol) used for the identification and quantification of trace impurities in APIs.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
