CATO supplies ((1S,3R,4R,7S)-3-Bromo-1,7-dimethyl-2-oxobicyclo[2.2.1]heptan-7-yl)methanesulfonic acid (CAS 46472-20-2), a certified reference material (molecular formula C10H15BrO4S, MW 311.19 g/mol) for analytical method development and quality control.
The molecular framework of ((1S,3R,4R,7S)-3-Bromo-1,7-dimethyl-2-oxobicyclo[2.2.1]heptan-7-yl)methanesulfonic acid (C10H15BrO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
