2-Methyl-3-butyn-2-amine(CAS: 2978-58-7)

2-Methyl-3-butyn-2-amine is a liquid at room temperature with a molecular weight of approximately 85.12 g/mol. It has a low solubility in water but is soluble in organic solvents. It is moderately reactive and can undergo electrophilic addition reactions. The compound is flammable and highly toxic by inhalation and skin contact.

2-Methyl-3-butyn-2-amine is typically synthesized by the reaction of 3-butyne with methylamine in the presence of a catalyst, such as palladium or platinum. The process involves electrophilic addition followed by amination. The yield is usually around 70-80%, and the method is selective for the desired product.

2-Methyl-3-butyn-2-amine is used in the pharmaceutical industry for the synthesis of certain drugs, particularly those involving alkyne functionalities. It is also utilized in the polymer industry for the production of specialty polymers, and in the sensor industry for the development of gas sensors.

When handling 2-Methyl-3-butyn-2-amine, proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat is essential. Work should be conducted in a fume hood to minimize inhalation risks. Spills should be cleaned up carefully using appropriate absorbents, and the area should be well-ventilated. Safety data sheets (SDS) should be consulted for detailed emergency procedures and storage guidelines.
