Description

Butylbenzene CAS NO 104-51-8 is a clear, colorless aromatic hydrocarbon belonging to the alkylbenzene family. This versatile organic intermediate is valued for its role as a precursor in chemical synthesis and as a high-boiling solvent in specialized formulations. It is primarily utilized by manufacturers in the chemical, polymer, and agrochemical industries for applications requiring a stable aromatic structure.

Application

• Chemical Synthesis Intermediate: A key building block for the production of specialty chemicals, including plasticizers, surfactants, and pharmaceuticals.
• Solvent for High-Temperature Reactions: Used as an inert, high-boiling point reaction medium in organic synthesis and polymerization processes.
• Polymer & Resin Production: Serves as a comonomer or chain transfer agent in the synthesis of certain specialty polymers and resins.
• Agrochemical Formulations: Employed as an intermediate in the manufacture of herbicides, pesticides, and other crop protection agents.
• Laboratory Reagent: Used in research and development as a standard or solvent for chromatography and spectroscopic analysis.
• Lubricant & Additive Component: Functions as a base fluid or additive in the formulation of high-performance synthetic lubricants and functional fluids.

Quality Control

Our Butylbenzene is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) for assay and impurity profiling, to meet exacting customer requirements. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
