3-(4-Bromo-1H-pyrazol-3-yl)pyridine (CAS 148138-02-7), molecular formula C8H6BrN3 and molecular weight 224.06 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Bromo-1H-pyrazol-3-yl)pyridine (C8H6BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine 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.
