Creatine Phosphate Impurity 13 CAS 1623-14-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Creatine Phosphate Impurity 13.

CATO supplies Creatine Phosphate Impurity 13 (CAS 1623-14-9), a pharmacopoeial impurity reference standard (molecular formula C2H7O4P, MW 126.05 g/mol) used for the identification and quantification of trace impurities in APIs.

Creatine Phosphate Impurity 13 (C2H7O4P) contains a phosphate ester group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, 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.

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.
