Description

Benzenemethanol, α-Methyl-4-Nitro-, (Alphas)- (9Ci) is a specialized chiral nitro-substituted benzyl alcohol derivative. This compound serves as a critical chiral building block and intermediate in advanced organic synthesis, particularly for the development of active pharmaceutical ingredients (APIs) and fine chemicals. It is essential for research and production facilities in the pharmaceutical, agrochemical, and specialty chemical industries that require high-purity, stereochemically defined intermediates for asymmetric synthesis and process chemistry.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the synthesis of complex drug molecules, especially those targeting neurological and cardiovascular pathways.
• Agrochemical Synthesis: Used in the research and development of novel, optically active pesticides and herbicides.
• Asymmetric Catalysis Research: Serves as a valuable ligand precursor or substrate in the development of new catalytic systems for stereoselective reactions.
• Fine Chemical Production: Employed in the manufacture of high-value specialty chemicals, including dyes, flavors, and fragrances requiring specific stereochemistry.
• Academic & R&D Laboratories: Utilized in organic chemistry research for method development and the study of nitro-aromatic compound behavior.

Quality Control

Our production of Benzenemethanol, α-Methyl-4-Nitro-, (Alphas)- (9Ci) adheres to stringent quality management protocols. Each batch is characterized and tested to ensure identity, purity, and enantiomeric excess meet exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing specific results for chiral purity (HPLC), chemical purity (HPLC/GC), and other critical parameters is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage.
