Chemical Structure

tert-Butyl (E)-17-bromo-4,7,10,13-tetraoxoheptadec-15-enoate CAS 166668-33-3 chemical structure

Description

Based on its molecular formula C17H31BrO6, tert-Butyl (E)-17-bromo-4,7,10,13-tetraoxoheptadec-15-enoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 411.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies tert-Butyl (E)-17-bromo-4,7,10,13-tetraoxoheptadec-15-enoate (CAS 166668-33-3), a certified reference material (molecular formula C17H31BrO6, MW 411.33 g/mol) for analytical method development and quality control.

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.
