Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 5-(5,5-Dimethyl-1,3-dioxan-2-yl)-1-(naphthalen-2-yl)pentan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
5-(5,5-Dimethyl-1,3-dioxan-2-yl)-1-(naphthalen-2-yl)pentan-1-one (CAS 898756-41-7), molecular formula C21H26O3 and molecular weight 326.43 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.
