Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 278.07 g/mol gives Methyl nonafluoropentanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl nonafluoropentanoate (CAS 13038-26-1), molecular formula C6H3F9O2 and molecular weight 278.07 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Methyl nonafluoropentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Methyl nonafluoropentanoate 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.
