653-37-2 S9YIE3JZ4K Pentafluorobenzaldehyde Benzaldehyde, pentafluoro- (8CI)(9CI) Benzaldehyde, 2,3,4,5,6-pentafluoro- EINECS 211-502-6 NSC 96967 2,3,4,5,6-Pentafluorobenzaldehyde UNII-S9YIE3JZ4K CAS 653-37-2 chemical structure

Description

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.

653-37-2 S9YIE3JZ4K Pentafluorobenzaldehyde Benzaldehyde, pentafluoro- (8CI)(9CI) Benzaldehyde, 2,3,4,5,6-pentafluoro- EINECS 211-502-6 NSC 96967 2,3,4,5,6-Pentafluorobenzaldehyde UNII-S9YIE3JZ4K (CAS 653-37-2), molecular formula C7H7F5O and molecular weight 202.12 g/mol, is a CATO reference standard with documented purity and traceability.

653-37-2 S9YIE3JZ4K Pentafluorobenzaldehyde Benzaldehyde, pentafluoro- (8CI)(9CI) Benzaldehyde, 2,3,4,5,6-pentafluoro- EINECS 211-502-6 NSC 96967 2,3,4,5,6-Pentafluorobenzaldehyde UNII-S9YIE3JZ4K (C7H7F5O) contains 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. 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.
