Description

2,3-Di-o-Para-Toluoyl-D-Tartaric Acid is a high-purity chiral resolving agent derived from D-tartaric acid. This compound is critically important for its ability to separate enantiomers of pharmaceutical intermediates and fine chemicals, ensuring the production of optically pure substances. It is primarily needed by manufacturers in the pharmaceutical, agrochemical, and advanced material synthesis industries for asymmetric synthesis and chiral resolution processes.

Application

• As a chiral resolving agent for the separation of racemic mixtures of amines, amino acids, and other basic pharmaceuticals.
• In the asymmetric synthesis of active pharmaceutical ingredients (APIs) and key intermediates.
• For the preparation of chiral stationary phases used in high-performance liquid chromatography (HPLC) for enantiomeric purity analysis.
• As a building block or catalyst in the research and development of novel optically active compounds.
• In the synthesis of specialty fine chemicals and ligands for asymmetric catalysis.
• For analytical standard preparation in quality control laboratories to verify enantiomeric excess.

Quality Control

Our 2,3-Di-o-Para-Toluoyl-D-Tartaric Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high chemical and optical purity, meeting the stringent requirements for chiral resolution applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific rotation is provided with every shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light exposure to maintain stability and purity.
