Amitriptyline EP Impurity C CAS 72-69-5 chemical structure

Description

Amitriptyline EP Impurity C (CAS 72-69-5) is a certified pharmaceutical impurity reference standard with the molecular formula C19H21N and a molecular weight of 263.38 g/mol.

Based on its molecular formula C19H21N, Amitriptyline EP Impurity C contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Amitriptyline EP Impurity C 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.
