Chemical Structure
Description
1-(1,1-Difluoropropyl)-2-methylbenzene (CAS 1890776-30-3), molecular formula C10H12F2 and molecular weight 170.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, an aromatic ring system, 1-(1,1-Difluoropropyl)-2-methylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 1-(1,1-Difluoropropyl)-2-methylbenzene 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.
