Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 1,4-Dibutoxy-2,5-diiodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 474.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1,4-Dibutoxy-2,5-diiodobenzene (CAS 145483-70-1), molecular formula C14H20I2O2 and molecular weight 474.12 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), 1,4-Dibutoxy-2,5-diiodobenzene 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.
