Description

Benzenemethanol, 5-Hydroxy-2-Nitroso- (9Ci) is a specialized aromatic compound featuring a unique nitroso and hydroxyl substitution pattern on the benzyl alcohol core. This structure makes it a valuable chemical intermediate and research reagent for synthesizing more complex molecules, particularly in advanced material science and pharmaceutical research. It is primarily needed by R&D chemists and process development scientists in the fine chemical, agrochemical, and pharmaceutical industries for building novel molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), especially those targeting specific receptor sites.
• Agrochemical Research: Used in the development and study of new herbicides, fungicides, or plant growth regulators due to its reactive functional groups.
• Dye and Pigment Synthesis: Acts as a precursor for creating specialized azo dyes and nitroso-based colorants with specific light-absorption properties.
• Coordination Chemistry & Ligand Synthesis: The nitroso and hydroxyl groups make it a candidate for designing chelating ligands for metal complexes used in catalysis or material science.
• Polymer Modification: Employed to introduce functional groups into polymer chains, altering properties like adhesion, solubility, or reactivity.
• Academic & Industrial R&D: A crucial reagent for methodological studies in organic synthesis, including nitrosation reactions and heterocycle formation.

Quality Control

Our production of Benzenemethanol, 5-Hydroxy-2-Nitroso- (9Ci) adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. While typically supplied as a research-grade material, specifications can be aligned with customer requirements. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
