Chemical Structure
Description
The occurrence of 3-Chloro-6-(2-chlorophenyl)pyridazine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloro-6-(2-chlorophenyl)pyridazine (CAS 66549-15-3) is a high-purity analytical reference standard with the molecular formula C10H6Cl2N2 and a molecular weight of 225.07 g/mol.
Structurally, 3-Chloro-6-(2-chlorophenyl)pyridazine (C10H6Cl2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 225.07 g/mol, it falls into the medium-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
