Description

D-(+)-Phenyllactic Acid is a high-purity, chiral organic acid characterized by its phenyl and lactic acid functional groups. This compound is valued for its role as a versatile chiral building block and intermediate in the synthesis of pharmaceuticals and fine chemicals. It is essential for research and production in the pharmaceutical, agrochemical, and food industries, where its stereochemical purity is critical for efficacy and safety.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for antibiotics, antivirals, and other therapeutic agents.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides, where the specific stereochemistry can influence biological activity.
• Food & Beverage Industry: Acts as a natural preservative and antimicrobial agent, inhibiting the growth of spoilage organisms like *Listeria*.
• Biochemical Research: Serves as a standard or substrate in enzymatic studies and metabolic pathway analysis.
• Flavor & Fragrance: Utilized as a building block for synthesizing specific aroma compounds and flavor enhancers.
• Cosmetic Ingredients: Incorporated into formulations for its skin-conditioning and potential preservative properties.

Quality Control

Our D-(+)-Phenyllactic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assay and impurity profiling, to ensure it meets the high standards required for pharmaceutical and food-grade applications. A Certificate of Analysis (COA) detailing specific results for identity, purity, and related substances is provided with every shipment.

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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties.
