349-50-8 Toluene, alpha-chloro-alpha,alpha-difluoro- 4-05-00-00814 (Beilstein Handbook Reference) Benzene, (chlorodifluoromethyl)- BRN 2041754 (Chlorodifluoromethyl)benzene omega-Chlorodifluorotoluene Difluorochlorotoluene (CAS 349-50-8), molecular formula C7H11ClF2 and molecular weight 168.61 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 349-50-8 Toluene, alpha-chloro-alpha,alpha-difluoro- 4-05-00-00814 (Beilstein Handbook Reference) Benzene, (chlorodifluoromethyl)- BRN 2041754 (Chlorodifluoromethyl)benzene omega-Chlorodifluorotoluene Difluorochlorotoluene (C7H11ClF2) contains fluorine/chlorine 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 168.61 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.

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.
