Benzoin tosylate

Description:
Benzoin tosylate, with the CAS number 1678-43-9, is an organic compound that serves as a versatile reagent in organic synthesis. It is characterized by the presence of a benzoin moiety esterified with a tosyl group, which enhances its reactivity. This compound typically appears as a white to off-white crystalline solid and is soluble in organic solvents such as dichloromethane and acetone, but has limited solubility in water. Benzoin tosylate is commonly used as a photoinitiator in polymerization reactions and as a precursor for various transformations, including the generation of benzoin derivatives. Its structure allows for the formation of radicals upon exposure to UV light, making it valuable in radical-mediated reactions. Additionally, it is known for its stability under standard laboratory conditions, although it should be handled with care due to the potential for irritation upon contact with skin or mucous membranes. Overall, benzoin tosylate is an important compound in synthetic organic chemistry, facilitating a range of chemical reactions.
