Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Hydroxy-3-methoxybenzyl 7-methyloctanoate (CAS 220012-53-3), molecular formula C17H26O4 and molecular weight 294.39 g/mol, is a CATO reference standard with documented purity and traceability.
4-Hydroxy-3-methoxybenzyl 7-methyloctanoate (C17H26O4) 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).
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.
