Description

o-Phenylenediamine, 3,6-Di-tert-Butyl- (8Ci) is a sterically hindered derivative of ortho-phenylenediamine, characterized by the presence of bulky tert-butyl groups at the 3 and 6 positions. This structural modification enhances its stability and makes it a valuable intermediate in the synthesis of high-performance polymers, dyes, and specialty chemicals. It is primarily sought after by R&D chemists and manufacturers in the polymer, agrochemical, and advanced material sectors for creating compounds with tailored properties.

Application

• Key monomer or chain extender in the synthesis of high-performance polyimides and polybenzimidazoles.
• Precursor for the manufacture of sterically hindered antioxidants and light stabilizers for plastics and rubber.
• Intermediate in the production of specialized dyes and pigments, particularly for high-temperature applications.
• Building block for ligands and catalysts used in organometallic chemistry and asymmetric synthesis.
• Raw material in agrochemical research for developing novel active ingredients.
• Component in the synthesis of corrosion inhibitors and other specialty additives for industrial fluids.

Quality Control

Our o-Phenylenediamine, 3,6-Di-tert-Butyl- is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay and impurity profiles. We support custom synthesis and can tailor specifications to meet specific R&D or production requirements.

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 flames. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
