Description
As a certified reference material (CRM), 2-Chloro-n-[4-(methylsulfanyl)phenyl]acetamide 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-n-[4-(methylsulfanyl)phenyl]acetamide (CAS 27978-30-9) is a high-purity analytical reference standard with the molecular formula C9H10ClNOS and a molecular weight of 215.70 g/mol.
The molecular framework of 2-Chloro-n-[4-(methylsulfanyl)phenyl]acetamide (C9H10ClNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
