Chemical Structure
Description
2-(4-Fluoro-1-methyl-1h-benzo[d]imidazol-2-yl)acetic acid, sodium salt (CAS 2490705-26-3) is a high-purity analytical reference standard with the molecular formula C10H9FN2O2Na and a molecular weight of 231.18 g/mol.
2-(4-Fluoro-1-methyl-1h-benzo[d]imidazol-2-yl)acetic acid, sodium salt (C10H9FN2O2Na) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, 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-(4-Fluoro-1-methyl-1h-benzo[d]imidazol-2-yl)acetic acid, sodium salt 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.
