Chemical Structure

2H,3H,5H-indeno[1,2-c]pyridazin-3-one CAS 69581-16-4 chemical structure

Description

2H,3H,5H-indeno[1,2-c]pyridazin-3-one (CAS 69581-16-4), molecular formula C11H18N2O and molecular weight 194.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2H,3H,5H-indeno[1,2-c]pyridazin-3-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 194.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 2H,3H,5H-indeno[1,2-c]pyridazin-3-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.
