Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 165.02 g/mol gives 3-(Chloromethyl)pyridazine Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Chloromethyl)pyridazine Hydrochloride (CAS 27349-66-2), molecular formula C5H5ClN2HCl and molecular weight 165.02 g/mol, is a CATO reference standard with documented purity and traceability.
3-(Chloromethyl)pyridazine Hydrochloride (C5H5ClN2HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3-(Chloromethyl)pyridazine Hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
