Chemical Structure
Description
3,4-Dichloro-3-iodobenzophenone (CAS 951891-47-7) is a high-purity analytical reference standard with the molecular formula C13H7Cl2IO and a molecular weight of 377.00 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system, 3,4-Dichloro-3-iodobenzophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 377.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3,4-Dichloro-3-iodobenzophenone 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.
