Chemical Structure
Description
The occurrence of Clomipramine EP Impurity C is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Clomipramine EP Impurity C (CAS 2095-42-3) is a certified pharmaceutical impurity reference standard with the molecular formula C19H21ClN2 and a molecular weight of 312.84 g/mol.
Structurally, Clomipramine EP Impurity C (C19H21ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 312.84 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 manufactures Clomipramine EP Impurity C under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
