CAS 927-80-0

Ethyne, ethoxy-

Description:

Ethyne, ethoxy- (CAS 927-80-0), also known as ethoxyacetylene, is an organic compound characterized by the presence of both an ethyne (acetylene) and an ethoxy functional group. It is a colorless, flammable liquid with a distinctive odor, commonly used in organic synthesis and as an intermediate in the production of various chemicals. The compound exhibits a linear structure due to the triple bond in the ethyne portion, contributing to its reactivity. Ethoxyacetylene is soluble in organic solvents but has limited solubility in water. It can participate in various chemical reactions, including nucleophilic additions and polymerizations, making it valuable in synthetic organic chemistry. Safety precautions are essential when handling this compound, as it is flammable and may pose health risks if inhaled or ingested. Proper storage in a cool, well-ventilated area away from ignition sources is recommended to mitigate hazards associated with its use.

Ethyl ethynyl ether - 40 wt. % in hexanes

CAS: 927-80-0

Ethyl ethynyl ether is a chemical compound that belongs to the class of amides. It has been shown to be a good model system for the understanding of polycarboxylic acids, which are important in inflammatory diseases. The preparation of this compound is carried out by reacting ethyl diazoacetate with hydrochloric acid and diacylglycerol in trifluoroacetic acid. This reaction produces a mixture containing ethyl ethynyl ether and ethyl diethynyl ether in a ratio of 1:3. The nitrogen atoms present in this molecule have been identified by magnetic resonance spectroscopy. In addition, the distance between these atoms was determined using NMR spectra and confirmed using preparative high-performance liquid chromatography (HPLC).
