Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-((2-Hydroxyethyl)thio)-1-(4-methoxyphenyl)ethan-1-one (CAS 1152910-36-5), molecular formula C11H14O3S and molecular weight 226.29 g/mol, is a CATO reference standard with documented purity and traceability.
2-((2-Hydroxyethyl)thio)-1-(4-methoxyphenyl)ethan-1-one (C11H14O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
