Chemical Structure
Description
1-Iodo-4-(prop-2-yn-1-yloxy)benzene (CAS 39735-76-7), molecular formula C9H7IO and molecular weight 258.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Iodo-4-(prop-2-yn-1-yloxy)benzene (C9H7IO) is characterized by a hydroxyl group, an ether linkage, 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).
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-Iodo-4-(prop-2-yn-1-yloxy)benzene 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.
