Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,3-Bis[(4-Fluorophenyl)-(4-Methylphenyl)Methyl]Urea (CAS 160807-91-0), molecular formula C29H26F2N2O and molecular weight 456.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1,3-Bis[(4-Fluorophenyl)-(4-Methylphenyl)Methyl]Urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 456.53 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), 1,3-Bis[(4-Fluorophenyl)-(4-Methylphenyl)Methyl]Urea 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.
