Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 196.24 g/mol gives 4-Methyl-[1,1'-biphenyl]-2-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Methyl-[1,1'-biphenyl]-2-carbaldehyde (CAS 2928-40-7), a certified reference material (molecular formula C14H12O, MW 196.24 g/mol) for analytical method development and quality control.
4-Methyl-[1,1'-biphenyl]-2-carbaldehyde (C14H12O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
