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-Iodo-2-methoxy-3,5-dimethylbenzene (CAS 65434-68-6), molecular formula C9H11IO and molecular weight 262.09 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Iodo-2-methoxy-3,5-dimethylbenzene (C9H11IO) contains a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 262.09 g/mol, it falls into the medium-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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
