Description
As a certified reference material (CRM), 3-Chloro-5-(pentan-2-yloxy)pyridazine 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.
CATO supplies 3-Chloro-5-(pentan-2-yloxy)pyridazine (CAS 1346691-21-1), a certified reference material (molecular formula C9H13ClN2O, MW 200.67 g/mol) for analytical method development and quality control.
3-Chloro-5-(pentan-2-yloxy)pyridazine (C9H13ClN2O) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
