Chemical Structure
Description
The occurrence of 2-Iodo-1,3,4-trimethylbenzene is closely related to iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Iodo-1,3,4-trimethylbenzene (CAS 41381-32-2), molecular formula C9H11I and molecular weight 246.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Iodo-1,3,4-trimethylbenzene (C9H11I) is characterized by 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
