Chemical Structure

tert-Butyl (3-bromo-4-methoxyphenyl)carbamate CAS 1489212-69-2 chemical structure

Description

The occurrence of tert-Butyl (3-bromo-4-methoxyphenyl)carbamate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies tert-Butyl (3-bromo-4-methoxyphenyl)carbamate (CAS 1489212-69-2), a certified reference material (molecular formula C12H16BrNO3, MW 302.16 g/mol) for analytical method development and quality control.

tert-Butyl (3-bromo-4-methoxyphenyl)carbamate (C12H16BrNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
