Description
CATO manufactures 1-Chloro-2-iodo-4-methoxybenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1-Chloro-2-iodo-4-methoxybenzene (CAS 2401-25-4), molecular formula C7H6ClIO and molecular weight 268.48 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Chloro-2-iodo-4-methoxybenzene (C7H6ClIO) contains a hydroxyl group, an ether linkage, chlorine/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 268.48 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
