Description
As a certified reference material (CRM), 4-[(3,4-difluorophenyl)methylidene]piperidine hydrochloride 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.
4-[(3,4-difluorophenyl)methylidene]piperidine hydrochloride (CAS 1803583-97-2), molecular formula C12H13F2NHCl and molecular weight 245.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-[(3,4-difluorophenyl)methylidene]piperidine hydrochloride (C12H13F2NHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
