Chemical Structure
Description
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.
CATO supplies 3',4',5'-Trimethoxy-[1,1'-biphenyl]-4-carbaldehyde (CAS 457616-23-8), a certified reference material (molecular formula C16H16O4, MW 272.30 g/mol) for analytical method development and quality control.
3',4',5'-Trimethoxy-[1,1'-biphenyl]-4-carbaldehyde (C16H16O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
