Description

2,4'-Dichloroazobenzene is an important organic intermediate belonging to the azobenzene class of compounds. This chemical matters for its role as a versatile building block in the synthesis of more complex molecules, particularly dyes, pigments, and functional materials. Industries such as specialty chemicals, advanced material research, and pharmaceutical development require this high-purity intermediate for their synthetic processes.

Application

• Dye and Pigment Intermediate: A key precursor in the synthesis of azo dyes and high-performance organic pigments.
• Liquid Crystal and OLED Material Research: Used in the development of photo-responsive and electro-optical materials for display technologies.
• Pharmaceutical Intermediate: Serves as a building block in the research and development of novel active pharmaceutical ingredients (APIs).
• Chemical Synthesis Reagent: Employed in organic synthesis for the introduction of the azobenzene moiety, useful in photochemistry studies.
• Polymer Modification: Can be used to functionalize polymers, imparting specific light-absorption or chromophoric properties.
• Analytical Chemistry Standard: Utilized as a reference standard in chromatographic analysis and method development.

Quality Control

Our 2,4'-Dichloroazobenzene is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, prolonged exposure to light should be avoided.
