Description

3-Aminophthalic Acid Hydrochloride is a key organic intermediate and building block in fine chemical synthesis. Its value lies in the dual functionality of the amine and carboxylic acid groups, which allows for versatile derivatization and incorporation into more complex molecular structures. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for developing active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those with heterocyclic or fused-ring structures.
• Agrochemical Synthesis: Serves as a precursor for developing herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Acts as a key component in the production of specialized dyes, fluorescent markers, and colorants.
• Luminescent Material Research: Utilized in the development of chemiluminescent compounds and organic light-emitting diodes (OLEDs).
• Polymer Modification: Employed to introduce functional groups into polymer chains to alter material properties like adhesion or solubility.
• Bioconjugation and Probe Synthesis: Used in life sciences for creating fluorescent probes and bioconjugation linkers.

Quality Control

Our 3-Aminophthalic Acid Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for use as a fine chemical intermediate. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
