Chemical Structure
Description
Structurally, 4-Chloro-3-(difluoromethoxy)benzaldehyde (C8H5ClF2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 206.57 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).
4-Chloro-3-(difluoromethoxy)benzaldehyde (CAS 2364584-99-4) is a high-purity analytical reference standard with the molecular formula C8H5ClF2O2 and a molecular weight of 206.57 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
