Chemical Structure
Description
4-Iodo-2-(2-methoxyphenyl)acetophenone (CAS 898784-93-5), molecular formula C15H13IO2 and molecular weight 352.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Iodo-2-(2-methoxyphenyl)acetophenone (C15H13IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 352.17 g/mol, it falls into the moderately-high-molecular-weight range. 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), 4-Iodo-2-(2-methoxyphenyl)acetophenone 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.
