Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methyl-3H-pyridazino[4,5-b]indol-4(5H)-one.
CATO supplies 3-Methyl-3H-pyridazino[4,5-b]indol-4(5H)-one (CAS 5777-93-5), a certified reference material (molecular formula C11H9N3O, MW 199.21 g/mol) for analytical method development and quality control.
Structurally, 3-Methyl-3H-pyridazino[4,5-b]indol-4(5H)-one (C11H9N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 199.21 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
