Chemical Structure

4,5-Dihydropyridazin-3(2H)-one CAS 61468-81-3 chemical structure

Description

4,5-Dihydropyridazin-3(2H)-one (CAS 61468-81-3), molecular formula C4H6N2O and molecular weight 98.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 4,5-Dihydropyridazin-3(2H)-one is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 98.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 4,5-Dihydropyridazin-3(2H)-one 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.
