Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Methyl 1-(4-fluorophenyl)-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylate (CAS 1011398-72-3) is a high-purity analytical reference standard with the molecular formula C20H14FN3O2 and a molecular weight of 347.34 g/mol.
Methyl 1-(4-fluorophenyl)-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylate (C20H14FN3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
CATO manufactures Methyl 1-(4-fluorophenyl)-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylate 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.
