Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 210.10 g/mol gives 2,6-Difluoro-3-(trifluoromethyl)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,6-Difluoro-3-(trifluoromethyl)benzaldehyde (CAS 134099-24-4) is a high-purity analytical reference standard with the molecular formula C8H3F5O and a molecular weight of 210.10 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2,6-Difluoro-3-(trifluoromethyl)benzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.10 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.
As a certified reference material (CRM), 2,6-Difluoro-3-(trifluoromethyl)benzaldehyde 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.
