Application

Chloral hydrate can be used as:
  • A reactant in the asymmetric synthesis of β-trichloromethyl-β-hydroxyketones by reacting with chiral imines.
  • A water carrier for the efficient deprotectionof acetals, dithioacetals, and tetrahydropyranyl ethers in organic solvents.
  • A reactant to synthesize 2-(hydroxyimino)-N-(2-iodophenyl)acetamide using 2-iodoaniline in the presence of hydrochloric acid, sodium sulfate, and hydroxyamine hydrochloride.
