Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2,6-Difluorophenyl)thiourea.
1-(2,6-Difluorophenyl)thiourea (CAS 59772-31-5), molecular formula C7H6F2N2S and molecular weight 188.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system, 1-(2,6-Difluorophenyl)thiourea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.20 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), 1-(2,6-Difluorophenyl)thiourea 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.
