Description

Isooctane CAS NO 26635-64-3 is a highly branched, saturated hydrocarbon widely recognized as a key reference standard for octane rating in fuels. Its exceptional chemical stability and defined combustion properties make it a critical component for precise analytical and calibration work. This high-purity solvent is essential for industries requiring reliable performance in research, quality control, and specialized manufacturing processes.

Application

• Fuel & Petroleum Reference Standard: Primary component for establishing 100 on the octane rating scale, used in engine testing and fuel formulation development.
• Analytical Chemistry & Chromatography: Serves as a high-purity solvent and mobile phase component in HPLC and GC analyses, particularly for non-polar compounds.
• Chemical Synthesis & Research: Used as an inert, non-polar reaction medium or solvent in organic synthesis and laboratory research.
• Polymer & Rubber Industry: Acts as a solvent for adhesives, coatings, and in the processing of certain elastomers and polymers.
• Calibration & Metrology: Employed as a certified reference material (CRM) for calibrating analytical instruments due to its well-defined physical properties.
• Industrial Cleaning: Utilized as a precision cleaning agent for optics, electronics, and mechanical parts where high volatility and low residue are required.

Quality Control

Our Isooctane is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including gas chromatography (GC), to verify identity, assay, and impurity profiles. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific customer or regulatory requirements, including those for reference fuel standards.

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 nature, keep container tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is between 15°C and 25°C.
