Description

Pentonic Acid, 2,3,5-Trideoxy-2-Ethyl-5-[(2-Hydroxyethyl)Amino]-5-Oxo-, γ-Lactone (9Ci) is a specialized lactone derivative with a unique molecular structure that combines a pentonic acid backbone with an ethyl and a hydroxyethylamino substituent. This compound is valued for its role as a versatile chiral building block and intermediate in advanced organic synthesis, particularly for pharmaceuticals and fine chemicals. It is essential for research and development chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce complex, functionalized lactone motifs into target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon for the development of active pharmaceutical ingredients (APIs), especially those targeting neurological or metabolic pathways.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and plant growth regulators requiring specific stereochemistry.
• Fine Chemical Production: Acts as a precursor for flavors, fragrances, and other high-value specialty chemicals where its lactone structure is integral.
• Biochemical Research: Employed as a substrate or inhibitor in enzymatic studies and for probing biological mechanisms due to its sugar acid-derived framework.
• Material Science: Potential monomer or cross-linking agent in the synthesis of novel biodegradable polymers and resins.

Quality Control

Every batch of our Pentonic Acid derivative is produced and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including HPLC, GC, and NMR. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with each shipment and are available upon request to support your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
