Chemical Structure
Description
The occurrence of Methyl 3-chloro-5h,6h,7h,8h-pyrido[4,3-c]pyridazine-6-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 3-chloro-5h,6h,7h,8h-pyrido[4,3-c]pyridazine-6-carboxylate (CAS 39716-01-3) is a high-purity analytical reference standard with the molecular formula C9H10ClN3O2 and a molecular weight of 227.65 g/mol.
Structurally, Methyl 3-chloro-5h,6h,7h,8h-pyrido[4,3-c]pyridazine-6-carboxylate (C9H10ClN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 227.65 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).
