Chemical Structure
Description
Methyl 3-((2-methoxy-2-oxoethyl)thio)-2-methylpropanoate (C8H14O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
Methyl 3-((2-methoxy-2-oxoethyl)thio)-2-methylpropanoate (CAS 38293-65-1), molecular formula C8H14O4S and molecular weight 206.26 g/mol, is a CATO reference standard with documented purity and traceability.
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.
