Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(4-chlorophenyl)-4-hydroxybenzamide (CAS 3679-68-3) is a high-purity analytical reference standard with the molecular formula C13H10ClNO2 and a molecular weight of 247.68 g/mol.
The molecular framework of N-(4-chlorophenyl)-4-hydroxybenzamide (C13H10ClNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), N-(4-chlorophenyl)-4-hydroxybenzamide 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.
