Chemical Structure
Description
2-((2,3-Dichlorophenyl)thio)ethan-1-ol (CAS 688762-59-6), molecular formula C8H8Cl2OS and molecular weight 223.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-((2,3-Dichlorophenyl)thio)ethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 2-((2,3-Dichlorophenyl)thio)ethan-1-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
