Chemical Structure
Description
CATO supplies 5-(1,3-Dioxolan-2-yl)-2-thienyl dodecyl ketone (CAS 898772-02-6), a certified reference material (molecular formula C20H32O3S, MW 352.53 g/mol) for analytical method development and quality control.
5-(1,3-Dioxolan-2-yl)-2-thienyl dodecyl ketone (C20H32O3S) contains a steroid core, a sulfone group, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
