Chemical Structure
Description
(2-Chloro-1,2-difluoroethenyl)benzene (CAS 10575-55-0), molecular formula C8H5ClF2 and molecular weight 174.58 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2-Chloro-1,2-difluoroethenyl)benzene (C8H5ClF2) contains fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 174.58 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.
CATO manufactures (2-Chloro-1,2-difluoroethenyl)benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
