Chemical Structure

2'-Ethynyl-[1,1'-biphenyl]-2-carbaldehyde CAS 121254-41-9 chemical structure

Description

2'-Ethynyl-[1,1'-biphenyl]-2-carbaldehyde (CAS 121254-41-9) is a high-purity analytical reference standard with the molecular formula C15H10O and a molecular weight of 206.24 g/mol.

Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2'-Ethynyl-[1,1'-biphenyl]-2-carbaldehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 206.24 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.

CATO manufactures 2'-Ethynyl-[1,1'-biphenyl]-2-carbaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
