As a certified reference material (CRM), Methyl 4,4-difluoro-2-hexynoate 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.
Methyl 4,4-difluoro-2-hexynoate (CAS 112780-02-6), molecular formula C7H8F2O2 and molecular weight 162.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 4,4-difluoro-2-hexynoate (C7H8F2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
