Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 160.17 g/mol gives Dimethyl(thiophen-3-yl)phosphine oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dimethyl(thiophen-3-yl)phosphine oxide (CAS 2926692-65-9), a certified reference material (molecular formula C6H9OPS, MW 160.17 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, Dimethyl(thiophen-3-yl)phosphine oxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
