Description

2-O,3-o-Diacetyltartaric Acid is a specialized organic acid derivative of tartaric acid, known for its role as a versatile intermediate and functional additive. This compound is valued for its ability to modify properties and act as a precursor in advanced chemical synthesis. It is primarily required by manufacturers in the pharmaceutical, food ingredient, and specialty chemical sectors for applications ranging from chiral synthesis to emulsification.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly where tartaric acid derivatives are required for chiral resolution or as a building block.
• Food Additive Precursor: Serves as a key intermediate in the production of emulsifiers and stabilizers, such as diacetyltartaric acid esters of mono- and diglycerides (DATEM).
• Chemical Synthesis: Acts as a protected form of tartaric acid in organic synthesis, facilitating reactions where the free acid groups need to be temporarily masked.
• Catalyst and Ligand Preparation: Utilized in the preparation of chiral catalysts and ligands for asymmetric synthesis.
• Polymer Modification: Employed as a modifying agent to introduce specific functional groups into polymer chains.
• Research & Development: Serves as a high-purity standard and reagent in analytical and process development laboratories.

Quality Control

Our 2-O,3-o-Diacetyltartaric Acid is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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 (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and stability.
