Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-fluorophenyl)-N-methylcarbamoyl chloride.
N-(4-fluorophenyl)-N-methylcarbamoyl chloride (CAS 55239-51-5), molecular formula C8H7ClFNO and molecular weight 187.60 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-fluorophenyl)-N-methylcarbamoyl chloride (C8H7ClFNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-(4-fluorophenyl)-N-methylcarbamoyl chloride 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.
