Description
As a certified reference material (CRM), 2,4-Dichloro-5-(difluoromethoxy)benzodifluoride 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.
2,4-Dichloro-5-(difluoromethoxy)benzodifluoride (CAS 1806296-73-0), molecular formula C8H4Cl2F4O and molecular weight 263.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,4-Dichloro-5-(difluoromethoxy)benzodifluoride (C8H4Cl2F4O) contains a hydroxyl group, an ether linkage, 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 263.02 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.
