Compared with other compounds in its class, the molecular weight of 118.15 g/mol gives 3-(Methylsulfonyl)prop-1-yne distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Methylsulfonyl)prop-1-yne (CAS 111247-76-8), molecular formula C4H6O2S and molecular weight 118.15 g/mol, is a CATO reference standard with documented purity and traceability.
3-(Methylsulfonyl)prop-1-yne (C4H6O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
