Chemical Structure
Description
The occurrence of 4-iodo-2,2,6,6-tetramethyl-tetrahydropyran is closely related to a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-iodo-2,2,6,6-tetramethyl-tetrahydropyran (CAS 1638768-38-3), a certified reference material (molecular formula C9H17IO, MW 268.14 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H17IO, 4-iodo-2,2,6,6-tetramethyl-tetrahydropyran 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 268.14 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.
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.
