Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 134102-10-6 Methyl 6-Fluoro-3,4-dihydro--4-oxo-2H-1-benzopyran-2-carboxylate rac-6-Fluoro-3,4-dihydro-4-oxo-2H-1-benzopyran-2-carboxylic Acid Methyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
134102-10-6 Methyl 6-Fluoro-3,4-dihydro--4-oxo-2H-1-benzopyran-2-carboxylate rac-6-Fluoro-3,4-dihydro-4-oxo-2H-1-benzopyran-2-carboxylic Acid Methyl Ester (CAS 134102-10-6), molecular formula C11H9FO4 and molecular weight 224.19 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), 134102-10-6 Methyl 6-Fluoro-3,4-dihydro--4-oxo-2H-1-benzopyran-2-carboxylate rac-6-Fluoro-3,4-dihydro-4-oxo-2H-1-benzopyran-2-carboxylic Acid Methyl Ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
