Description
CATO manufactures Ethyl 5,5-difluoro-4-oxopentanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Ethyl 5,5-difluoro-4-oxopentanoate (CAS 1161004-57-4), a certified reference material (molecular formula C7H10F2O3, MW 180.15 g/mol) for analytical method development and quality control.
Structurally, Ethyl 5,5-difluoro-4-oxopentanoate (C7H10F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 180.15 g/mol, it falls into the medium-molecular-weight range. 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.
