Description

(R)-(-)-1-Phenylethyl 3,5-Dinitrobenzoate CAS NO 3205-33-2 is a high-purity chiral chemical derivative of 3,5-dinitrobenzoic acid, serving as a critical resolving agent and chiral auxiliary in asymmetric synthesis. Its primary value lies in its ability to facilitate the separation and purification of enantiomers, a fundamental process in the development of single-isomer pharmaceuticals and advanced materials. This compound is essential for research and production teams in the pharmaceutical, agrochemical, and fine chemical industries who require reliable, high-quality chiral building blocks for their synthetic workflows.

Application

• Chiral Resolution Agent: Used for the separation of racemic mixtures of amines, alcohols, and other chiral compounds via diastereomeric salt formation or derivatization.
• Pharmaceutical Intermediate: Serves as a key chiral auxiliary in the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs).
• Analytical Chemistry Standard: Employed as a reference standard in HPLC and chiral chromatography for method development and calibration.
• Asymmetric Synthesis: Acts as a building block or catalyst ligand in stereoselective chemical reactions.
• Agrochemical Research: Utilized in the development of chiral pesticides and herbicides where specific stereochemistry impacts biological activity.
• Academic & Industrial R&D: A valuable tool for research laboratories exploring new methodologies in organic and medicinal chemistry.
