Chemical Structure
Description
2-Methyl-[1,1'-biphenyl]-4-carbaldehyde (CAS 1256468-34-4) is a high-purity analytical reference standard with the molecular formula C14H12O and a molecular weight of 196.24 g/mol.
The molecular framework of 2-Methyl-[1,1'-biphenyl]-4-carbaldehyde (C14H12O) is characterized by a hydroxyl group, an ether linkage, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
