Description
As a certified reference material (CRM), Methyl 4'-cyano-[1,1'-biphenyl]-3-carboxylate 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.
Methyl 4'-cyano-[1,1'-biphenyl]-3-carboxylate (CAS 149505-91-9), molecular formula C15H11NO2 and molecular weight 237.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 4'-cyano-[1,1'-biphenyl]-3-carboxylate (C15H11NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
