Description

[S,(-)]-2-(Trimethylaminio)Propanoic Acid Ion is a high-purity, chiral quaternary ammonium compound, also known as L-Carnitine inner salt. This compound is essential as a key intermediate and reference standard in the synthesis of pharmaceuticals and advanced biochemicals. It is primarily required by manufacturers in the pharmaceutical, nutraceutical, and fine chemical industries for producing L-carnitine and its derivatives, which are critical for metabolic processes.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of L-Carnitine and its pharmaceutical salts (e.g., L-Carnitine L-tartrate).
• Reference Standard: Used as a high-purity analytical standard for quality control and method development in pharmaceutical testing laboratories.
• Nutraceutical Production: Serves as a direct precursor in the manufacture of high-grade dietary supplements and clinical nutrition products.
• Biochemical Research: Employed in metabolic studies and enzymatic research due to its role in fatty acid transport.
• Chiral Synthesis: Utilized in asymmetric synthesis and the production of enantiomerically pure compounds for advanced medicinal chemistry.
