Description

D-Tarb-No2, 2-(3-Nitrophenyl)-1,3,2-Dioxaborolane-4S,5S-Dicarboxylic Acid is a high-value, stereochemically defined boronic ester derivative, serving as a critical chiral building block in modern organic synthesis. Its core value lies in enabling the stereoselective construction of complex molecules, which is essential for developing pharmaceuticals and advanced materials. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications in asymmetric synthesis and cross-coupling reactions.

Application

• Pharmaceutical Intermediate: Key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• Suzuki-Miyaura Cross-Coupling Reactions: Acts as a stable, air- and moisture-tolerant organoboron reagent for forming carbon-carbon bonds with high enantiomeric purity.
• Asymmetric Catalysis: Used as a ligand or auxiliary in catalytic systems to induce chirality in target molecules.
• Agrochemical Research: Building block for developing novel, stereospecific herbicides, fungicides, and insecticides.
• Material Science: Precursor for creating chiral polymers or organic frameworks with unique optical or electronic properties.
• Academic & Industrial R&D: Essential tool compound for methodological development in synthetic organic chemistry laboratories.

Quality Control

Every batch of D-Tarb-No2 is produced under strict quality management protocols to ensure consistency and purity for sensitive synthetic applications. Our products undergo rigorous quality testing, including chiral purity verification, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing specific tests such as chiral HPLC, NMR, and elemental analysis are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition.
