1,2-DIFLUORO-3-METHYL-BENZENE 2,3-DIFLUORO METHYL BENZENE 2,3-DIFLUORO-PHENYLAMINE 2,3-DIFLUOROBENZENAMINE 2,3-DIFLUOROTOLUENE 2,3-Difluoroaniline 4519-40-8 AS00340 TIMTEC-BB SBB006565 CAS 4519-40-8 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.

1,2-DIFLUORO-3-METHYL-BENZENE 2,3-DIFLUORO METHYL BENZENE 2,3-DIFLUORO-PHENYLAMINE 2,3-DIFLUOROBENZENAMINE 2,3-DIFLUOROTOLUENE 2,3-Difluoroaniline 4519-40-8 AS00340 TIMTEC-BB SBB006565 (CAS 4519-40-8), molecular formula C6H11F2N and molecular weight 135.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,2-DIFLUORO-3-METHYL-BENZENE 2,3-DIFLUORO METHYL BENZENE 2,3-DIFLUORO-PHENYLAMINE 2,3-DIFLUOROBENZENAMINE 2,3-DIFLUOROTOLUENE 2,3-Difluoroaniline 4519-40-8 AS00340 TIMTEC-BB SBB006565 (C6H11F2N) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 135.16 g/mol, it falls into the low-molecular-weight range. 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.
