Chemical Structure

Penehyclidine impurity 29 CAS 860804-18-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 410.40 g/mol gives Penehyclidine impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Penehyclidine impurity 29 (CAS 860804-18-8), a pharmacopoeial impurity reference standard (molecular formula C21H32NO2Br, MW 410.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C21H32NO2Br, Penehyclidine impurity 29 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 410.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
