(S)-3-(tert-Butyl)-4-(2,6-diisopropoxyphenyl)-2,3-dihydrobenzo[d][1,3]oxaphosphole CAS 2448341-44-2

Description

Compared with other compounds in its class, the molecular weight of 386.46 g/mol gives (S)-3-(tert-Butyl)-4-(2,6-diisopropoxyphenyl)-2,3-dihydrobenzo[d][1,3]oxaphosphole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-3-(tert-Butyl)-4-(2,6-diisopropoxyphenyl)-2,3-dihydrobenzo[d][1,3]oxaphosphole (CAS 2448341-44-2), a certified reference material (molecular formula C23H31O3P, MW 386.46 g/mol) for analytical method development and quality control.

Owing to a steroid core, a phosphonate group, a hydroxyl group, an ether linkage, (S)-3-(tert-Butyl)-4-(2,6-diisopropoxyphenyl)-2,3-dihydrobenzo[d][1,3]oxaphosphole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
