Description

Benzoic Acid, 5-Amino-2-[(3-Hydroxypropyl)Amino]- (9Ci) is a specialized amino-functionalized benzoic acid derivative with significant potential as a versatile chemical intermediate. This compound matters for its unique bifunctional structure, which combines a reactive aromatic amine group with a terminal hydroxyl group, enabling its use in the synthesis of complex molecules. It is primarily needed by research and development chemists in the pharmaceutical and advanced materials sectors for creating novel active ingredients, dyes, and functional polymers.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for compounds targeting specific receptors or requiring tailored solubility profiles.
• Dye and Pigment Synthesis: Serves as a precursor for azo dyes and other colorants, where its amino and carboxylic acid groups allow for coupling and modification to achieve specific hues and properties.
• Polymer and Resin Modifier: Used to introduce functional amine and hydroxyl groups into polymer backbones, enhancing properties like adhesion, cross-linking density, or biocompatibility in specialty coatings and resins.
• Chelating Agent Precursor: Its structure is suitable for development into ligands and chelating agents for metal ions, useful in catalysis, water treatment, or analytical chemistry.
• Bioconjugation Linker: Employed in biochemical research for creating conjugates between proteins, peptides, or other biomolecules and reporter molecules or solid supports.
• Organic Synthesis Reagent: A valuable reagent in academic and industrial R&D for constructing complex heterocycles and other organic molecules due to its two distinct reactive sites.

Quality Control

Our Benzoic Acid, 5-Amino-2-[(3-Hydroxypropyl)Amino]- (9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
