Chemical Structure

Di-n-propyl sulfite CAS 623-98-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 166.24 g/mol gives Di-n-propyl sulfite distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Di-n-propyl sulfite (CAS 623-98-3), a certified reference material (molecular formula C6H14O3S, MW 166.24 g/mol) for analytical method development and quality control.

Di-n-propyl sulfite (C6H14O3S) 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.

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.
