2-(2-((Tetrahydro-2h-pyran-4-yl)oxy)ethoxy)ethane-1-sulfonyl chloride CAS 1343631-98-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 272.75 g/mol gives 2-(2-((Tetrahydro-2h-pyran-4-yl)oxy)ethoxy)ethane-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2-((Tetrahydro-2h-pyran-4-yl)oxy)ethoxy)ethane-1-sulfonyl chloride (CAS 1343631-98-0), molecular formula C9H17ClO5S and molecular weight 272.75 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2-((Tetrahydro-2h-pyran-4-yl)oxy)ethoxy)ethane-1-sulfonyl chloride (C9H17ClO5S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
