Chemical Structure
Description
As a certified reference material (CRM), 2-([1,1'-biphenyl]-4-yl)-6-methylbenzo[b]thiophene 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.
2-([1,1'-biphenyl]-4-yl)-6-methylbenzo[b]thiophene (CAS 22720-99-6), molecular formula C21H16S and molecular weight 300.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-([1,1'-biphenyl]-4-yl)-6-methylbenzo[b]thiophene (C21H16S) is characterized by sulfur-containing functionality, 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.
