Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-[(2E)-3-[4-(Propan-2-yl)phenyl]prop-2-enoyl]phenyl 2,4,6-trimethylbenzene-1-sulfonate (CAS 331461-19-9), a certified reference material (molecular formula C27H28O4S, MW 448.57 g/mol) for analytical method development and quality control.
4-[(2E)-3-[4-(Propan-2-yl)phenyl]prop-2-enoyl]phenyl 2,4,6-trimethylbenzene-1-sulfonate (C27H28O4S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
