Chemical Structure
Description
The occurrence of (1R,2R)-2-(4-(methylthio)benzoyl)cyclohexane-1-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (1R,2R)-2-(4-(methylthio)benzoyl)cyclohexane-1-carboxylic acid (CAS 844856-85-5), a certified reference material (molecular formula C15H18O3S, MW 278.37 g/mol) for analytical method development and quality control.
(1R,2R)-2-(4-(methylthio)benzoyl)cyclohexane-1-carboxylic acid (C15H18O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
