Description

Benzene CAS NO 71-43-2 is a fundamental aromatic hydrocarbon and a key building block in industrial organic chemistry. Its primary commercial value lies in its role as a precursor to numerous essential chemicals, polymers, and materials. This highly volatile solvent is indispensable for manufacturers in the petrochemical, plastics, and pharmaceutical sectors, where it serves as a critical raw material for synthesis and processing.

Application

• Chemical Synthesis: Primary feedstock for the production of ethylbenzene (for styrene and polystyrene), cumene (for phenol and acetone), cyclohexane (for nylon), and maleic anhydride.
• Plastics & Resins Manufacturing: Essential monomer in the production of various polymers and synthetic rubbers.
• Solvent Applications: Used as an industrial solvent in the formulation of paints, coatings, adhesives, and for extraction processes, though its use is highly regulated.
• Pharmaceutical Intermediates: Serves as a starting material in the synthesis of certain active pharmaceutical ingredients (APIs) and dyes.
• Detergent Alkylate Production: Used in the manufacture of linear alkylbenzene sulfonates (LABS), a key component in biodegradable detergents.

Quality Control

Our Benzene is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and purity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as purity, water content, and impurity profiles. Quality specifications are aligned with major industrial and reagent-grade standards to meet the rigorous demands of downstream chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and flammable nature, containers must be kept tightly sealed and grounded during handling to prevent vapor accumulation and static discharge. Store separately from strong oxidizing agents.
