Description

(R)-(+)-1,2-Heptanediol is a high-purity chiral diol building block, distinguished by its specific (R)-(+) enantiomeric configuration. This precise stereochemistry is critical for applications requiring high enantiomeric excess (ee) and predictable biological or chemical activity. It serves as a valuable intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors, where chiral purity directly impacts product efficacy and regulatory approval.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of enantiomerically pure drugs.
• Agrochemical Synthesis: Used in the production of chiral pesticides, herbicides, and plant growth regulators where specific stereoisomers exhibit enhanced activity.
• Asymmetric Catalysis: Employed as a ligand or precursor for chiral catalysts and auxiliaries in stereoselective organic synthesis.
• Flavor and Fragrance Industry: Serves as a building block for the synthesis of chiral aroma chemicals and flavor compounds.
• Polymer Chemistry: Acts as a monomer or chain extender for creating specialized polyesters and polyurethanes with tailored properties.
• Cosmetic Ingredients: Potential use in the synthesis of specialty humectants or emollients with specific sensory profiles.
• Chemical Research: A valuable standard and reagent in academic and industrial R&D for studying stereochemistry and developing new synthetic methodologies.

Quality Control

Our (R)-(+)-1,2-Heptanediol is produced under strict quality management systems. Each batch is characterized and tested to ensure high chemical and chiral purity, with critical parameters including assay, enantiomeric excess (ee), and identity verified. Certificates of Analysis (COA) detailing specifications and test results (e.g., by HPLC, GC, chiral chromatography, and optical rotation) are provided to guarantee consistency and traceability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to minimize moisture absorption. Recommended long-term storage at 2-8°C.
