As a certified reference material (CRM), 2-Chloro-n-{4-[(difluoromethyl)sulfanyl]phenyl}propanamide 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-[(difluoromethyl)sulfanyl]phenyl}propanamide (CAS 929973-61-5), molecular formula C10H10ClF2NOS and molecular weight 265.71 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-Chloro-n-{4-[(difluoromethyl)sulfanyl]phenyl}propanamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.71 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.
