Description
As a certified reference material (CRM), Ethyl 3,5-dichloro-2-iodobenzoate 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.
Ethyl 3,5-dichloro-2-iodobenzoate (CAS 939989-95-4), molecular formula C9H7Cl2IO2 and molecular weight 344.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 3,5-dichloro-2-iodobenzoate (C9H7Cl2IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 344.96 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.
