Description

2-Hydroxyethyl(Trimethyl)Ammonium n-Acetyl-L-Methionate is a high-purity, specialized organic salt derived from the amino acid methionine. This compound is valued for its role as a stable, bioavailable source of methionine and its cationic, hygroscopic properties. It is primarily utilized in the formulation of advanced pharmaceuticals, nutraceuticals, and high-performance cosmetic and personal care products where controlled delivery and stability are critical.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and as a precursor for specialized drug delivery systems.
• Nutraceutical & Dietary Supplements: Serves as a bioavailable source of L-methionine in premium-grade supplements for metabolic and liver support.
• Cosmetic Actives: Incorporated into advanced skincare and haircare formulations for its moisturizing (hygroscopic) and potential keratin-strengthening properties.
• Biochemical Research: Employed as a reagent or standard in biochemical studies and analytical method development.
• Specialty Chemical Synthesis: Acts as a building block or catalyst in organic synthesis for fine chemicals and agrochemicals.
