Chemical Structure
Description
The occurrence of 4-Fluoro-7-methoxy-1H-indazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Fluoro-7-methoxy-1H-indazole (CAS 1000341-74-1), molecular formula C8H7FN2O and molecular weight 166.15 g/mol, is a CATO reference standard with documented purity and traceability.
4-Fluoro-7-methoxy-1H-indazole (C8H7FN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
