Description

2-Hydroxybutyric Acid is a versatile chiral hydroxy acid with significant utility in fine chemical synthesis and biochemical research. Its value lies in its role as a key building block for pharmaceuticals, agrochemicals, and advanced materials, offering a reactive site for further functionalization. This compound is essential for R&D chemists and production managers in the pharmaceutical, flavor & fragrance, and specialty chemical industries seeking high-purity intermediates.

Application

• Pharmaceutical Intermediate: A crucial chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs targeting metabolic pathways.
• Flavor and Fragrance Ingredient: Used in the production of esters and lactones that contribute to creamy, buttery, or fruity notes in food flavors and perfumery.
• Biochemical Research: Serves as a standard or reagent in metabolic studies, particularly related to ketone body metabolism and energy homeostasis.
• Agrochemical Synthesis: Employed as a building block for creating herbicides, fungicides, and plant growth regulators with specific stereochemistry.
• Polymer Modification: Acts as a monomer or co-monomer for producing biodegradable polyesters or for introducing hydroxyl functionality into polymer chains.
• Cosmetic Ingredients: Used in the synthesis of skin-conditioning agents and emulsifiers for personal care formulations.
