Chemical Structure
Description
2-tert-butyl-5-iodopyridin-4-ol (CAS 2092475-20-0) is a high-purity analytical reference standard with the molecular formula C9H12INO and a molecular weight of 277.10 g/mol.
2-tert-butyl-5-iodopyridin-4-ol (C9H12INO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
