Description

L(+)-Tartaric Acid is a naturally occurring, white crystalline dicarboxylic acid widely valued for its chiral properties and versatile functionality. It serves as a crucial chiral building block and acidulant, offering superior optical purity and consistent performance. This high-quality ingredient is essential for manufacturers in the pharmaceutical, food and beverage, and fine chemical industries seeking reliable, high-purity raw materials for their critical processes.

Application

• Pharmaceutical Industry: Used as a chiral resolving agent for separating racemic mixtures, a key component in effervescent tablets, and as an excipient in various drug formulations.
• Food & Beverage Additive (E334): Functions as a natural acidulant, flavor enhancer, and stabilizer in wines, candies, jellies, and baking powders.
• Chemical Synthesis: Employed as a precursor and chiral auxiliary in asymmetric synthesis for producing fine chemicals and active pharmaceutical ingredients (APIs).
• Cosmetics & Personal Care: Acts as an α-hydroxy acid (AHA) in skincare products for its exfoliating and pH-adjusting properties.
• Electroplating & Metal Surface Treatment: Serves as a complexing agent in electroplating baths and for metal cleaning and polishing.
• Laboratory & Analytical Reagent: Utilized in buffer solutions and as a standard in various analytical and biochemical applications.

Quality Control

Our L(+)-Tartaric Acid is manufactured under strict quality management systems to ensure it meets the highest standards. We offer grades compliant with major pharmacopoeias, including USP-NF, EP, BP, and FCC for food applications. Every batch is supported by a comprehensive Certificate of Analysis (COA) verifying identity, purity, and specific optical rotation, ensuring traceability and reliability for your B2B supply chain.

Storage

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