Description

3-Aminonaphthalene-2-Carboxaldehyde is a specialized aromatic aldehyde derivative that serves as a versatile building block in advanced organic synthesis. Its unique bifunctional structure, featuring both an amine and an aldehyde group on the naphthalene ring, makes it a critical intermediate for constructing complex heterocyclic and fluorescent compounds. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries developing novel active ingredients and functional dyes.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and anti-cancer agents.
• Fluorescent Probe Synthesis: Core building block for creating naphthalimide-based fluorescent dyes and sensors used in bioimaging and diagnostic assays.
• Agrochemical Research: Intermediate in the development of new herbicides and pesticides with enhanced efficacy and selectivity.
• Material Science: Used in the synthesis of organic semiconductors, liquid crystals, and photochromic materials for advanced electronic applications.
• Chemical Research: Valuable reagent for heterocyclic chemistry, enabling the construction of complex quinoline, acridine, and other fused ring systems.
• Dye and Pigment Manufacturing: Intermediate for producing high-performance, light-fast organic pigments and dyes.

Quality Control

Our 3-Aminonaphthalene-2-Carboxaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods for structural confirmation. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support cGMP standards for pharmaceutical applications and can tailor purity grades to meet specific research or production requirements.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
