Application
(-)-Dibenzoyl-L-tartaric acid monohydrate is a high-efficiency chiral resolving agent widely used in pharmaceutical and fine chemical industries. Its core application lies in the chiral resolution of racemic amines, amino acids, and other chiral nitrogen-containing compounds, forming diastereomeric salts with different solubility for separation via recrystallization. It is critical for producing single-enantiomer drugs, especially in the synthesis of β-lactam antibiotics, antihistamines, and central nervous system agents. In organic synthesis, it serves as a chiral catalyst and resolving auxiliary for asymmetric reactions, enhancing enantioselectivity. It also acts as a chiral standard for HPLC and polarimetry calibration in analytical chemistry. With stable properties and low cost, it supports large-scale industrial production and academic research on chiral mechanism, playing an irreplaceable role in modern chiral chemistry.
Safety Information
This compound is classified as a mild irritant (GHS Category 2A for eye irritation). It may cause redness, pain, and temporary blurred vision upon eye contact; prolonged skin contact may trigger mild irritation or allergic reactions. No acute toxicity is reported, but inhalation of dust may irritate the respiratory tract. It is incompatible with strong bases and oxidants, which may cause decomposition. Wear chemical-resistant gloves, safety goggles, and dust mask during handling; avoid direct contact and inhalation. In case of eye contact, rinse continuously with water for 15 minutes and seek medical attention. Store in a dry, cool place away from incompatible substances. Dispose of waste in accordance with local regulations to prevent environmental contamination. Follow standard laboratory safety protocols to minimize exposure risks.
