Chemical Structure
Description
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.
CATO supplies (7,7-Dimethyl-2,3-dioxobicyclo[2.2.1]Heptan-1-yl)methanesulfonic acid hydrate (CAS 73413-79-3), a certified reference material (molecular formula C10H14O5SH2O, MW 264.29 g/mol) for analytical method development and quality control.
The molecular framework of (7,7-Dimethyl-2,3-dioxobicyclo[2.2.1]Heptan-1-yl)methanesulfonic acid hydrate (C10H14O5SH2O) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
