Description

3,5-o-[(S)-Phenylmethylene]-, γ-Lactone D-Xylonic Acid is a specialized chiral intermediate and a derivative of D-xylonic acid. This compound matters for its role as a key building block in the synthesis of complex molecules, particularly in pharmaceutical research and fine chemical manufacturing. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for developing new active ingredients and chiral catalysts.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), especially in antiviral and anti-inflammatory drug candidates.
• Asymmetric Catalyst Precursor: Serves as a starting material for the synthesis of chiral ligands and organocatalysts used in stereoselective synthesis.
• Fine Chemical Synthesis: Used in the multi-step synthesis of complex natural product analogs and other high-value specialty chemicals.
• Biochemical Research: Employed in studies related to carbohydrate chemistry and the development of enzyme inhibitors or glycomimetics.
• Agrochemical Development: Potential intermediate in the creation of new, more selective herbicides or plant growth regulators.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized using advanced analytical techniques to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing specific results for chiral purity (enantiomeric excess), assay, and related substances are available upon request. We adhere to cGMP principles for the manufacture of critical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which may affect stability and handling properties.
