( R )-(+)-LACTAMIDE(CAS: 598-81-2)

(R)-2-Hydroxypropanamide, also known as (R)-lactamide, is a white crystalline solid with a molecular weight of approximately 102.12 g/mol. It is sparingly soluble in water but highly soluble in organic solvents like ethanol and acetone. This compound is amphoteric in nature and exhibits moderate reactivity, particularly in nucleophilic substitution reactions. It has a pKa of around 8.5, indicating basic properties in aqueous solutions.

(R)-2-Hydroxypropanamide can be synthesized via the hydrolysis of the corresponding (R)-2-aminopropanoyl chloride. The reaction typically involves treating the chloride with a strong base like sodium hydroxide in a polar aprotic solvent like dimethylformamide (DMF) at room temperature. The yield is generally around 75-85%, with good stereochemical control and high enantiomeric purity.

(R)-2-Hydroxypropanamide is widely used in the pharmaceutical industry as an intermediate in the synthesis of various drugs. It also finds applications in the polymer industry, where it serves as a crosslinking agent, and in the development of sensors and semiconductors due to its amphoteric properties and reactivity.

When handling (R)-2-Hydroxypropanamide, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. The compound should be stored in a cool, dry place away from direct sunlight and heat sources. In case of spillage, it should be carefully and thoroughly cleaned up with appropriate absorbent materials. Exposure to this compound should be avoided, and an SDS (Safety Data Sheet) should be consulted for detailed safety guidelines and emergency procedures.
