Chemical Structure

Prostaglandin Impurity 32 CAS CATO-C4X-199632 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 32 (CAS CATO-C4X-199632), a pharmacopoeial impurity reference standard (molecular formula C20H34O5, MW 354.48 g/mol) used for the identification and quantification of trace impurities in APIs.

Prostaglandin Impurity 32 (C20H34O5) 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 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).

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.
