Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 231.26 g/mol gives Oxybenzone-d3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Oxybenzone-d3 (CAS CATO-CCHM704668) is a high-purity analytical reference standard with the molecular formula C14H9D3O3 and a molecular weight of 231.26 g/mol.
Oxybenzone-d3 (C14H9D3O3) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, 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.
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.
