Chemical Structure

1-((7AR)-8,8-dimethyl-1,1-dioxidohexahydro-4H-3a,6-methanobenzo[d]isothiazol-7-yl)but-2-en-1-one CAS 94668-55-0 chemical structure

Description

The molecular framework of 1-((7AR)-8,8-dimethyl-1,1-dioxidohexahydro-4H-3a,6-methanobenzo[d]isothiazol-7-yl)but-2-en-1-one (C14H21NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies 1-((7AR)-8,8-dimethyl-1,1-dioxidohexahydro-4H-3a,6-methanobenzo[d]isothiazol-7-yl)but-2-en-1-one (CAS 94668-55-0), a certified reference material (molecular formula C14H21NO3S, MW 283.39 g/mol) for analytical method development and quality control.

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.
