Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3'-Chloro-3,4,5-trimethoxy-1,1'-biphenyl.
3'-Chloro-3,4,5-trimethoxy-1,1'-biphenyl (CAS 942475-05-0), molecular formula C15H15ClO3 and molecular weight 278.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3'-Chloro-3,4,5-trimethoxy-1,1'-biphenyl (C15H15ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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.
As a certified reference material (CRM), 3'-Chloro-3,4,5-trimethoxy-1,1'-biphenyl 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.
