Description
As a certified reference material (CRM), 2-Chloro-n-[2-(difluoromethoxy)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-[2-(difluoromethoxy)phenyl]propanamide (CAS 929973-76-2) is a high-purity analytical reference standard with the molecular formula C10H10ClF2NO2 and a molecular weight of 249.64 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-Chloro-n-[2-(difluoromethoxy)phenyl]propanamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.64 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
