Chemical Structure
Description
The occurrence of Decyl 5-(1,3-dioxolan-2-yl)-2-thienyl ketone is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Decyl 5-(1,3-dioxolan-2-yl)-2-thienyl ketone (CAS 898771-98-7), molecular formula C18H28O3S and molecular weight 324.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Decyl 5-(1,3-dioxolan-2-yl)-2-thienyl ketone (C18H28O3S) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
