Chemical Structure

4-Iodotetrahydro-2H-pyran CAS 25637-18-7 chemical structure

Description

4-Iodotetrahydro-2H-pyran (CAS 25637-18-7), molecular formula C5H9IO and molecular weight 212.03 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H9IO, 4-Iodotetrahydro-2H-pyran contains a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 212.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 4-Iodotetrahydro-2H-pyran 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.
