Chemical Structure
Description
As a certified reference material (CRM), 2-Chloro-1-[4-(methylsulfanyl)phenyl]ethan-1-one 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.
2-Chloro-1-[4-(methylsulfanyl)phenyl]ethan-1-one (CAS 109607-24-1), molecular formula C9H9ClOS and molecular weight 200.69 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-1-[4-(methylsulfanyl)phenyl]ethan-1-one (C9H9ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, 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. 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.
