Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 170.64 g/mol gives 3-tert-Butyl-6-chloropyridazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-tert-Butyl-6-chloropyridazine (CAS 41144-46-1), molecular formula C8H11ClN2 and molecular weight 170.64 g/mol, is a CATO reference standard with documented purity and traceability.
3-tert-Butyl-6-chloropyridazine (C8H11ClN2) contains a nitrogen-containing heterocyclic scaffold, 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. 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.
