Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,4-Difluoro-5-methylbenzotrifluoride (CAS 1806370-13-7), molecular formula C8H5F5 and molecular weight 196.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, an aromatic ring system, 3,4-Difluoro-5-methylbenzotrifluoride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.12 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.
CATO manufactures 3,4-Difluoro-5-methylbenzotrifluoride 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.
