Description

L-Threonic Acid is a four-carbon sugar acid and a key metabolite of vitamin C (ascorbic acid). This compound is valued for its chelating and antioxidant properties, making it a versatile intermediate in advanced synthesis. It is primarily sought by manufacturers in the pharmaceutical, nutraceutical, and cosmetic industries for applications ranging from mineral supplements to advanced skincare formulations. Our supply of L-Threonic Acid CAS NO 7306-96-9 ensures high purity and batch-to-batch consistency for critical production processes.

Application

• Pharmaceutical Intermediates: Used in the synthesis of novel therapeutic agents and as a building block for chiral molecules.
• Nutraceutical & Dietary Supplements: Incorporated as a bioactive component in mineral chelates (e.g., magnesium L-threonate) for enhanced bioavailability and cognitive support formulas.
• Cosmetic & Personal Care: Employed in anti-aging and skincare products for its antioxidant and skin-conditioning properties.
• Food & Beverage Additives: Functions as a natural acidulant and stabilizer in certain food systems.
• Chemical Synthesis: Serves as a chiral starting material or ligand in asymmetric synthesis and catalysis.
• Research & Development: Utilized in biochemical research as a standard or reagent for metabolic studies.
