Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,6-Dichloro-4-iodobenzaldehyde (CAS 177167-53-2), molecular formula C7H3Cl2IO and molecular weight 300.91 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Dichloro-4-iodobenzaldehyde (C7H3Cl2IO) is characterized by a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2,6-Dichloro-4-iodobenzaldehyde 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.
