Chemical Structure
Description
Structurally, Trihexyphenidyl Impurity 14 HCl (C20H29NHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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 319.92 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Trihexyphenidyl Impurity 14 HCl (CAS 344890-62-6 (free base)) is a certified pharmaceutical impurity reference standard with the molecular formula C20H29NHCl and a molecular weight of 319.92 g/mol.
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.
