Description

9-Amino-7-Chloro-1,3-Dimethylpyrido[1,2-A]Benzimidazole-4-Carboxylic Acid Sodium Salt is a high-purity, complex heterocyclic compound serving as a critical synthetic intermediate. Its value lies in its functionalized benzimidazole-pyridine fused ring system, which is essential for constructing advanced molecular architectures. This product is primarily needed by research institutions and pharmaceutical development companies engaged in the synthesis of novel active pharmaceutical ingredients (APIs) and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block in the research and development of new therapeutic agents, particularly those targeting specific enzymatic pathways.
• Organic Synthesis Research: Used in academic and industrial R&D for constructing complex heterocyclic scaffolds and studying structure-activity relationships (SAR).
• Agrochemical Development: Potential intermediate in the synthesis of novel fungicides or herbicides due to its chlorinated benzimidazole core.
• Dye and Pigment Precursor: Serves as a specialized intermediate for synthesizing high-performance, color-fast dyes and functional pigments.
• Material Science Research: Investigated for use in creating organic electronic materials or metal-organic frameworks (MOFs) with unique photophysical properties.

Quality Control

Our production of 9-Amino-7-Chloro-1,3-Dimethylpyrido[1,2-A]Benzimidazole-4-Carboxylic Acid Sodium Salt adheres to stringent quality management protocols. Every batch is analyzed using advanced chromatographic and spectroscopic techniques to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and residual solvents is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect stability and handling properties. Keep away from incompatible materials.
