Chemical Structure
Description
CATO supplies 4-Hydroxy-3-(3-methylbut-2-en-1-yl)-6-pentadecyl-2H-pyran-2-one (CAS 83725-44-4), a certified reference material (molecular formula C25H42O3, MW 390.60 g/mol) for analytical method development and quality control.
4-Hydroxy-3-(3-methylbut-2-en-1-yl)-6-pentadecyl-2H-pyran-2-one (C25H42O3) contains a steroid 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.
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.
