Chemical Structure
Description
4-[(4-Formyl-3-hydroxyphenoxy)methyl]benzoic acid (C15H12O5) contains a flavonoid core, a hydroxyl group, an ether linkage. 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).
4-[(4-Formyl-3-hydroxyphenoxy)methyl]benzoic acid (CAS 866143-85-3), molecular formula C15H12O5 and molecular weight 272.25 g/mol, is a CATO reference standard with documented purity and traceability.
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.
