Chemical Structure
Description
1-((4-Chlorophenyl)(phenyl)methyl)-4-methylpiperazine dihydrochloride (CAS 129-71-5) is a high-purity analytical reference standard with the molecular formula C18H21ClN2HCl and a molecular weight of 337.29 g/mol.
The molecular framework of 1-((4-Chlorophenyl)(phenyl)methyl)-4-methylpiperazine dihydrochloride (C18H21ClN2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-((4-Chlorophenyl)(phenyl)methyl)-4-methylpiperazine dihydrochloride 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.
