Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2,3-Difluorophenyl)methanamine (CAS 72235-51-9) is a high-purity analytical reference standard with the molecular formula C7H7F2N and a molecular weight of 143.13 g/mol.
Owing to a nitrile group, fluorine substitution, an aromatic ring system, (2,3-Difluorophenyl)methanamine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.13 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).
As a certified reference material (CRM), (2,3-Difluorophenyl)methanamine 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.
