Aminoadipic acid

Updated: 2026-09-16

Overview

Aminoadipic acid (AAA) is a non-proteinogenic amino acid that serves as an intermediate in the lysine degradation pathway. It is structurally similar to other dicarboxylic acids but contains an additional amino group. This compound is not incorporated into proteins but plays a significant role in biochemical processes, particularly in the metabolism of lysine. Aminoadipic acid is primarily used in research and industrial applications. Its unique properties make it valuable in pharmaceutical synthesis and as a precursor for other chemical compounds. The compound is typically synthesized through chemical or enzymatic methods, depending on the desired purity and application.

Physical and Chemical Properties

Aminoadipic acid appears as a white crystalline powder with a molecular weight of 161.16 g/mol. It has a melting point of approximately 205-210°C, at which point it begins to decompose. The compound is soluble in water and slightly soluble in ethanol, making it versatile for various applications. The chemical stability of aminoadipic acid is influenced by storage conditions. It should be kept in a cool, dry environment, away from light and moisture to prevent degradation. The compound's solubility and stability are critical factors in its use in pharmaceutical and biochemical applications.

Main Applications

Aminoadipic acid is widely used in pharmaceutical synthesis, where it serves as a building block for more complex molecules. Its role in the lysine degradation pathway also makes it a subject of interest in biochemical research, particularly in studies related to amino acid metabolism. In addition to its pharmaceutical applications, aminoadipic acid is used in the food industry as an additive. It can act as a flavor enhancer or preservative, depending on the formulation. The compound's versatility and relatively low toxicity make it suitable for a range of industrial uses.

Safety and Storage

Proper handling and storage of aminoadipic acid are essential to ensure its stability and safety. The compound should be stored in a cool, dry place, away from light and moisture. Exposure to high temperatures or humidity can lead to degradation, reducing its efficacy for industrial or research purposes. Safety precautions include wearing appropriate personal protective equipment (PPE), such as gloves and goggles, when handling the compound. Inhalation, ingestion, or skin contact should be avoided. In case of exposure, immediate medical attention may be required, depending on the severity of the incident.

B2B Procurement Guide

When procuring aminoadipic acid, it is crucial to verify the supplier's credentials and the quality of the product. Request certificates of analysis (CoA) and material safety data sheets (MSDS) to ensure the compound meets your specifications and safety requirements. Consider factors such as purity, packaging, and price when selecting a supplier. The reference price range for aminoadipic acid is approximately $50-$200 per kilogram, depending on purity and supplier. Bulk purchases may offer cost savings, but ensure the supplier can meet your volume and delivery requirements.
