Chemical Structure
Description
212890-35-2 2H-Pyran, 2-[(1R)-1-[2-(2,4-difluorophenyl)oxiranyl]ethoxy]tetrahydro- CTK0J7763 (CAS 212890-35-2) is a high-purity analytical reference standard with the molecular formula C15H18F2O3 and a molecular weight of 284.30 g/mol.
212890-35-2 2H-Pyran, 2-[(1R)-1-[2-(2,4-difluorophenyl)oxiranyl]ethoxy]tetrahydro- CTK0J7763 (C15H18F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 212890-35-2 2H-Pyran, 2-[(1R)-1-[2-(2,4-difluorophenyl)oxiranyl]ethoxy]tetrahydro- CTK0J7763 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.
