Chemical Structure
Description
The occurrence of Tert-butyl (2-iodo-4-methoxyphenyl)carbamate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Tert-butyl (2-iodo-4-methoxyphenyl)carbamate (CAS 157496-75-8), a certified reference material (molecular formula C12H16INO3, MW 349.16 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H16INO3, Tert-butyl (2-iodo-4-methoxyphenyl)carbamate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 349.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
