Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 412.37 g/mol gives Ipratropium Impurity 14 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ipratropium Impurity 14 (CAS CATO-C4X-166514), a pharmacopoeial impurity reference standard (molecular formula C20H30NO3Br, MW 412.37 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Ipratropium Impurity 14 (C20H30NO3Br) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 412.37 g/mol, it falls into the moderately-high-molecular-weight range. 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.
