Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-amino-3,5-difluorobenzene-1-carboximidamide dihydrochloride (CAS 1803588-95-5), molecular formula C7H7F2N3HCl and molecular weight 207.61 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine/chlorine substitution, an aromatic ring system, 4-amino-3,5-difluorobenzene-1-carboximidamide dihydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.61 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), 4-amino-3,5-difluorobenzene-1-carboximidamide dihydrochloride 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.
