Chemical Structure
Description
CATO supplies 3,5-Dichloro-2-fluorotoluene (CAS 146948-70-1), a certified reference material (molecular formula C7H5Cl2F, MW 179.02 g/mol) for analytical method development and quality control.
Structurally, 3,5-Dichloro-2-fluorotoluene (C7H5Cl2F) contains fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 179.02 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3,5-Dichloro-2-fluorotoluene 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.
