Chemical Structure
Description
N-Hydroxy-1-methylpyrazole-4-carbimidoyl Chloride (CAS 1282486-64-9) is a high-purity analytical reference standard with the molecular formula C5H6ClN3O and a molecular weight of 159.57 g/mol.
N-Hydroxy-1-methylpyrazole-4-carbimidoyl Chloride (C5H6ClN3O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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-Hydroxy-1-methylpyrazole-4-carbimidoyl 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.
