Description

4-Aminophthalonitrile is a high-purity, versatile aromatic nitrile derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both an amino and two nitrile groups, makes it an essential precursor for the development of complex heterocyclic compounds and functional materials. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty dyes industries, where it is used to create phthalocyanines, fluorescent markers, and other high-value intermediates.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with phthalocyanine or quinazoline backbones.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators.
• Functional Dyes & Pigments: Core building block for the production of phthalocyanine dyes, which are used in inks, coatings, and optical data storage.
• Material Science: Intermediate in the creation of organic semiconductors, conductive polymers, and metal-organic frameworks (MOFs).
• Fluorescent Probe Synthesis: Utilized to develop fluorescent markers and sensors for biological imaging and diagnostic applications.
• Research & Development: Serves as a versatile starting material in academic and industrial R&D for exploring new chemical entities and reaction pathways.

Quality Control

Our 4-Aminophthalonitrile is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and FTIR, to confirm identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes. We adhere to cGMP principles where applicable, and our quality systems are designed to meet the stringent requirements of the pharmaceutical and fine chemical industries.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light exposure to maintain stability and purity.
