Penehyclidine impurity 12 CAS 151673-91-5

Description

Compared with other compounds in its class, the molecular weight of 206.28 g/mol gives Penehyclidine impurity 12 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Penehyclidine impurity 12 (CAS 151673-91-5), a pharmacopoeial impurity reference standard (molecular formula C13H18O2, MW 206.28 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Penehyclidine impurity 12 (C13H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
