Chemical Structure

4'-Methyl-[1,1'-biphenyl]-2-carbaldehyde CAS 16191-28-9 chemical structure

Description

CATO supplies 4'-Methyl-[1,1'-biphenyl]-2-carbaldehyde (CAS 16191-28-9), a certified reference material (molecular formula C14H12O, MW 196.24 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4'-Methyl-[1,1'-biphenyl]-2-carbaldehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 196.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4'-Methyl-[1,1'-biphenyl]-2-carbaldehyde 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.
