Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Sodium (2Z)-4-(2-fluorophenyl)-1-methoxy-1,4-dioxobut-2-en-2-olate (CAS 2034161-81-2), molecular formula C11H8FO4Na and molecular weight 246.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Sodium (2Z)-4-(2-fluorophenyl)-1-methoxy-1,4-dioxobut-2-en-2-olate (C11H8FO4Na) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
