Chemical Structure
Description
CATO supplies (4-Chloro-2,3-dimethylphenyl)(methyl)sulfane (CAS 2432936-55-3), a certified reference material (molecular formula C9H11ClS, MW 186.70 g/mol) for analytical method development and quality control.
(4-Chloro-2,3-dimethylphenyl)(methyl)sulfane (C9H11ClS) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
