5,5-difluoro-2-methoxycarbonyl-pentanoic acid CAS 1782836-42-3

Description

Compared with other compounds in its class, the molecular weight of 196.15 g/mol gives 5,5-difluoro-2-methoxycarbonyl-pentanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,5-difluoro-2-methoxycarbonyl-pentanoic acid (CAS 1782836-42-3), molecular formula C7H10F2O4 and molecular weight 196.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5,5-difluoro-2-methoxycarbonyl-pentanoic acid (C7H10F2O4) 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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
