Chemical Structure
Description
Gentamicin C2b Pentatrifluoroacetate (C20H41N5O7C2HF3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Gentamicin C2b Pentatrifluoroacetate (CAS 52093-21-7 (free base)) is a high-purity analytical reference standard with the molecular formula C20H41N5O7C2HF3O2 and a molecular weight of 577.60 g/mol.
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.
