Description

Carbazole CAS NO 86-74-8 is a versatile heterocyclic aromatic organic compound characterized by a tricyclic structure consisting of two benzene rings fused on either side of a pyrrole ring. It serves as a fundamental building block and key intermediate in the synthesis of high-value dyes, pigments, and advanced electronic materials. This compound is essential for manufacturers and R&D teams in the pharmaceutical, agrochemical, and specialty chemical industries seeking reliable, high-purity raw materials.

Application

• Dye and Pigment Intermediate: A crucial precursor for the synthesis of carbazole-based dyes, including Hydron Blue and other vat dyes, as well as high-performance pigments.
• Pharmaceutical Synthesis: Used as a key starting material or intermediate in the production of various active pharmaceutical ingredients (APIs) and fine chemicals.
• Electroluminescent Materials: Serves as a core structure for host and emitter materials in Organic Light-Emitting Diodes (OLEDs) and other optoelectronic devices due to its good hole-transporting properties.
• Photoconductive Agents: Employed in the manufacturing of photoconductive polymers and materials used in photocopiers and laser printers.
• Agrochemical Production: Acts as an intermediate in the synthesis of certain pesticides and plant growth regulators.
• Corrosion Inhibition: Utilized in the formulation of corrosion inhibitors for industrial applications, particularly in acidic environments.
• Research & Development: A valuable compound for academic and industrial research in organic chemistry, materials science, and medicinal chemistry.

Quality Control

Our Carbazole is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We offer various grades, including technical and purified grades, to meet diverse industrial requirements. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, melting point, and impurity profiles. Our quality commitment aligns with ISO standards, and we can support compliance documentation for REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized (store under inert atmosphere), it is recommended to keep the container sealed under an inert gas such as nitrogen after opening to maintain product integrity and prevent degradation. Keep away from heat, sparks, and open flame.
