Chemical Structure
Description
2-(3-Fluorophenyl)-4-methoxypyrazolo[1,5-a]pyrazine-3-carbaldehyde (CAS 1708178-75-9), molecular formula C14H10FN3O2 and molecular weight 271.25 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3-Fluorophenyl)-4-methoxypyrazolo[1,5-a]pyrazine-3-carbaldehyde (C14H10FN3O2) contains a nitrogen-containing heterocyclic scaffold, 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.
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.
CATO manufactures 2-(3-Fluorophenyl)-4-methoxypyrazolo[1,5-a]pyrazine-3-carbaldehyde 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.
