5-Decyne(CAS: 1942-46-7)

5-Decyne (CAS: 1942-46-7) is a colorless, volatile liquid with a pungent odor. Its molecular weight is approximately 114.21 g/mol. It is slightly soluble in water but miscible with most organic solvents. Chemically, it is relatively stable but can undergo polymerization under certain conditions. It has a vapor pressure of about 1 mm Hg at 25°C and a flash point of 16°C.

5-Decyne (CAS: 1942-46-7) can be synthesized through the Wittig reaction, where triphenylphosphine and methyl acrylate react to form the desired product. Alternatively, it can be produced via the hydroboration-oxidation of an alkene. The yield is generally high, and the reaction is carried out under mild conditions using suitable catalysts.

5-Decyne (CAS: 1942-46-7) is used in various industries, including pharmaceuticals for intermediates in drug synthesis, polymers for specialty plastics, and sensors for detecting organic compounds. It is also used in the semiconductor industry as a precursor for organometallic compounds.

5-Decyne (CAS: 1942-46-7) should be handled with care due to its volatility and flammability. Use appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. Store in a cool, dry place away from sources of ignition. In case of a spill, use a fume hood and follow standard hazardous waste disposal procedures. Refer to the Safety Data Sheet (SDS) for detailed guidance.
