Chemical Structure

Trihexyphenidyl Impurity 13 CAS 4352-39-0 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 Trihexyphenidyl Impurity 13 (CAS 4352-39-0), a pharmacopoeial impurity reference standard (molecular formula C14H20O, MW 204.31 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H20O, Trihexyphenidyl Impurity 13 contains a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), Trihexyphenidyl Impurity 13 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
