Chemical Structure

Prostaglandin Impurity 29 CAS 42935-17-1 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.

CATO supplies Prostaglandin Impurity 29 (CAS 42935-17-1), a pharmacopoeial impurity reference standard (molecular formula C20H32O5, MW 352.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Prostaglandin Impurity 29 (C20H32O5) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
