Chemical Structure

tert-Butyl (2-(4-bromo-2-fluorophenoxy)ethyl)(cyclopropyl)carbamate CAS 1704081-73-1 chemical structure

Description

The occurrence of tert-Butyl (2-(4-bromo-2-fluorophenoxy)ethyl)(cyclopropyl)carbamate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies tert-Butyl (2-(4-bromo-2-fluorophenoxy)ethyl)(cyclopropyl)carbamate (CAS 1704081-73-1), a certified reference material (molecular formula C16H21BrFNO3, MW 374.25 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, tert-Butyl (2-(4-bromo-2-fluorophenoxy)ethyl)(cyclopropyl)carbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures tert-Butyl (2-(4-bromo-2-fluorophenoxy)ethyl)(cyclopropyl)carbamate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
