The occurrence of 1-(2,4-Dichlorophenyl)ethane-1-thiol is closely related to sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(2,4-Dichlorophenyl)ethane-1-thiol (CAS 1039319-82-8), a certified reference material (molecular formula C8H8Cl2S, MW 207.12 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, chlorine substitution, an aromatic ring system, 1-(2,4-Dichlorophenyl)ethane-1-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
