Description

(+)-Carnitine Benzyl Ester Chloride CAS NO 14548-21-1 is a high-purity, chiral benzyl-protected derivative of L-carnitine, a vital compound in cellular energy metabolism. This intermediate is crucial for the synthesis of pharmaceutical-grade L-carnitine and its analogs, offering a protected form that facilitates specific chemical transformations. It is primarily required by manufacturers in the pharmaceutical, nutraceutical, and fine chemical industries for research, development, and production of metabolic and cardiovascular therapeutics.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of L-carnitine and its pharmaceutical salts (e.g., L-carnitine L-tartrate).
• Active Pharmaceutical Ingredient (API) Synthesis: Used in the production of APIs for drugs targeting metabolic disorders, such as primary and secondary carnitine deficiencies.
• Nutraceutical Manufacturing: Serves as a protected precursor in the industrial-scale production of high-purity L-carnitine for dietary supplements and clinical nutrition products.
• Biochemical Research: Employed in metabolic pathway studies and as a standard in analytical method development for carnitine analogs.
• Fine Chemical Synthesis: Valuable intermediate for creating novel carnitine esters and other derivatives with potential therapeutic applications.
• Cosmetic & Dermatological Preparations: Potential use as an intermediate for ingredients in formulations targeting skin energy metabolism.
