Description

5,7-Diamino-8-Hydroxy-Carbostyril Dihydrochloride is a high-purity, functionalized carbostyril derivative primarily used as a key synthetic intermediate or building block in advanced chemical synthesis. Its value lies in the unique reactivity imparted by its diamine and phenolic hydroxyl groups, which are essential for constructing complex heterocyclic systems. This compound is particularly critical for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it serves in the development of novel active ingredients and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of novel drug candidates, particularly in oncology and anti-infective research.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and plant growth regulators.
• Dye & Pigment Precursor: Serves as a starting material for creating specialized heterocyclic dyes and organic pigments.
• Coordination Chemistry Ligand: Its structure allows it to act as a chelating agent for metal ions in catalytic and material science applications.
• Fluorescent Probe Development: Utilized in research to create molecular probes for bioimaging and diagnostic assays due to its carbostyril core.
• Organic Electronic Materials: Investigated as a component in the synthesis of materials for organic light-emitting diodes (OLEDs) and semiconductors.

Quality Control

Every batch of 5,7-Diamino-8-Hydroxy-Carbostyril Dihydrochloride is manufactured under strict quality management systems and undergoes comprehensive analytical testing. We ensure compliance with stringent internal specifications suitable for research and commercial synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Long-term storage under inert atmosphere is recommended.
