tert-Butyl 4-iodo-5-methoxypyridin-3-ylcarbamate CAS 1045858-08-9

Description

Compared with other compounds in its class, the molecular weight of 356.20 g/mol gives tert-Butyl 4-iodo-5-methoxypyridin-3-ylcarbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies tert-Butyl 4-iodo-5-methoxypyridin-3-ylcarbamate (CAS 1045858-08-9), a certified reference material (molecular formula C11H21IN2O3, MW 356.20 g/mol) for analytical method development and quality control.

Structurally, tert-Butyl 4-iodo-5-methoxypyridin-3-ylcarbamate (C11H21IN2O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 356.20 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
