Chemical Structure

Prostaglandin Impurity 17 CAS 63319-59-5 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 17 (CAS 63319-59-5), a pharmacopoeial impurity reference standard (molecular formula C7H6Cl2O, MW 177.03 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Prostaglandin Impurity 17 (C7H6Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 177.03 g/mol, it falls into the medium-molecular-weight range. 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.
