Description

(Z)-Azobenzene is the cis-isomer of the azobenzene family, a class of organic compounds characterized by a nitrogen-nitrogen double bond linking two phenyl rings. This specific stereoisomer is a valuable photo-switchable molecule and a key synthetic intermediate in advanced materials science. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for developing light-responsive systems and functional dyes.

Application

• Molecular Switches & Photo-responsive Materials: Core component in the design of light-controlled systems for data storage, sensors, and actuators.
• Pharmaceutical Research Intermediate: Used in the synthesis and study of novel drug candidates and bioactive molecules.
• Dye & Pigment Manufacturing: Serves as a precursor for azo dyes and pigments, contributing to colorant development.
• Liquid Crystal & Polymer Science: Incorporated into materials to induce photo-alignment and modify optical properties.
• Chemical Biology Probes: Enables the creation of tools for studying biological processes with light activation.
• Academic & Industrial R&D: Fundamental building block for research in photochemistry and supramolecular chemistry.

Quality Control

Our (Z)-Azobenzene is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and isomer specificity. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature, prolonged exposure to light should be avoided to prevent isomerization to the trans-form.
