(Difluoromethyl)benzene (CAS 455-31-2) is a high-purity analytical reference standard with the molecular formula C7H6F2 and a molecular weight of 128.12 g/mol.
Owing to fluorine substitution, an aromatic ring system, (Difluoromethyl)benzene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (Difluoromethyl)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
