Chemical Structure
Description
86356-73-2 formaldehyde O-perfluorobenzyl oxime o-(2,3,4,5,6-Pentafluorobenzyl)formaldoxime (CAS 86356-73-2), molecular formula C8H10F5NO and molecular weight 231.16 g/mol, is a CATO reference standard with documented purity and traceability.
86356-73-2 formaldehyde O-perfluorobenzyl oxime o-(2,3,4,5,6-Pentafluorobenzyl)formaldoxime (C8H10F5NO) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
