Description

Sodium L-Rhamnonate is the sodium salt of L-rhamnonic acid, a sugar acid derivative. This specialized biochemical is valued for its role as a key chiral intermediate and building block in advanced organic synthesis and pharmaceutical research. It is primarily utilized by research institutions and manufacturers in the pharmaceutical, fine chemical, and life science sectors for developing novel compounds and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A critical chiral precursor in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a standard or reagent in enzymatic studies, metabolic pathway analysis, and carbohydrate chemistry research.
• Fine Chemical Synthesis: Serves as a building block for the production of specialty chemicals, including surfactants, chelating agents, and other rhamnose derivatives.
• Cosmetic & Personal Care: Potential application as a mild, skin-compatible ingredient or a precursor for moisturizing agents and emulsifiers.
• Food Science Research: Investigated for use as a dietary supplement precursor or a metabolic tracer in nutritional studies.

Quality Control

Our Sodium L-Rhamnonate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, optical rotation, and impurity profiles. Specifications can be tailored to meet research-grade or higher purity requirements upon request.

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); ensure the container is sealed immediately after use to prevent absorption of atmospheric moisture.
