Chemical Structure

7-Ethyl-1,2,3,4-tetrahydropyrido[2,3-d]pyridazin-8(7H)-one CAS 1447949-61-2 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

7-Ethyl-1,2,3,4-tetrahydropyrido[2,3-d]pyridazin-8(7H)-one (CAS 1447949-61-2), molecular formula C9H13N3O and molecular weight 179.22 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, 7-Ethyl-1,2,3,4-tetrahydropyrido[2,3-d]pyridazin-8(7H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 179.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

As a certified reference material (CRM), 7-Ethyl-1,2,3,4-tetrahydropyrido[2,3-d]pyridazin-8(7H)-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.
