Chemical Structure
Description
1,4-Diethynyl-2,5-bis(trifluoromethyl)benzene (CAS 1084895-80-6) is a high-purity analytical reference standard with the molecular formula C12H4F6 and a molecular weight of 262.15 g/mol.
Owing to fluorine substitution, an aromatic ring system, 1,4-Diethynyl-2,5-bis(trifluoromethyl)benzene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 262.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 1,4-Diethynyl-2,5-bis(trifluoromethyl)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.
