Description

2-Hydroxyethyl(Trimethyl)Ammonium n-Acetyl-Dl-Methionate is a high-purity quaternary ammonium salt derivative of methionine, a sulfur-containing amino acid. This compound is valued for its role as a specialized intermediate in the synthesis of advanced pharmaceutical actives and high-value fine chemicals. It is particularly relevant for manufacturers in the pharmaceutical, nutraceutical, and specialty chemical sectors seeking reliable, high-quality building blocks for complex synthesis.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of specialized active pharmaceutical ingredients (APIs), particularly those requiring methionine-derived structures.
• Biochemical Research: Used as a reagent or precursor in life science research for studying metabolic pathways and protein synthesis.
• Nutraceutical Synthesis: Intermediate in the production of advanced amino acid supplements and specialized nutritional compounds.
• Cosmetic Ingredient Synthesis: Serves as a precursor for the manufacture of certain conditioning agents or skin-active ingredients in high-end cosmetic formulations.
• Chiral Chemistry: The DL-methionate structure makes it relevant for applications in chiral synthesis and resolution processes.
• Surfactant & Specialty Chemical Production: Potential use as an intermediate for synthesizing novel quaternary ammonium-based surfactants or ionic liquids.

Quality Control

Our 2-Hydroxyethyl(Trimethyl)Ammonium n-Acetyl-Dl-Methionate is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, impurity profile, and moisture content. We adhere to cGMP principles where applicable to meet the stringent requirements of our pharmaceutical and research customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect quality.
