Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Oxepanone, polymer with 4,4'-(1-methylethylidene)bis[phenol] (CAS 52609-48-0) is a high-purity analytical reference standard with the molecular formula C15H16O2C6H10O2 and a molecular weight of 342.44 g/mol.
2-Oxepanone, polymer with 4,4'-(1-methylethylidene)bis[phenol] (C15H16O2C6H10O2) 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).
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.
