Description

2-Amino-4-Hydroxypyridine Hydrochloride is a high-purity organic salt derivative of aminohydroxypyridine, serving as a critical building block in advanced chemical synthesis. Its value lies in providing a functionalized pyridine core with both amino and hydroxyl groups, protected as a stable hydrochloride salt for improved handling and reactivity. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing novel active ingredients and complex heterocyclic intermediates.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, especially those targeting central nervous system (CNS) disorders and infectious diseases.
• Agrochemical Synthesis: Building block for developing advanced herbicides, fungicides, and plant growth regulators with pyridine-based structures.
• Ligand and Catalyst Development: Used to create chelating ligands for metal catalysis in fine chemical and asymmetric synthesis processes.
• Material Science Research: Serves as a monomer or functional additive in the development of specialty polymers and advanced organic materials.
• Chemical Reference Standard: High-purity grade is utilized as an analytical standard for quality control and method development in regulatory testing.

Quality Control

Our 2-Amino-4-Hydroxypyridine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and stringent controls for residual solvents and heavy metals. Certificates of Analysis (COA) documenting full compliance with in-house specifications are available upon request for every shipment.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
