Description

Decahydronaphthalene is a saturated bicyclic hydrocarbon, a fully hydrogenated derivative of naphthalene, widely recognized for its excellent solvent properties and chemical stability. This high-purity solvent is valued for its ability to dissolve a wide range of organic compounds while offering a favorable balance of volatility and safety. It serves as a critical intermediate and processing aid in the production of specialty chemicals, polymers, and advanced materials for industries including pharmaceuticals, agrochemicals, coatings, and electronics.

Application

• Industrial Solvent: An effective solvent for resins, waxes, oils, and fats in coatings, adhesives, and cleaning formulations.
• Chemical Intermediate: Used in the synthesis of dyes, pigments, and other complex organic molecules.
• Polymer & Plasticizer Production: Acts as a reaction medium or starting material in the manufacture of certain polymers and plasticizers.
• Electronics Manufacturing: Employed as a precision cleaning agent for electronic components and circuit boards.
• Fuel & Lubricant Additive: Serves as a component or precursor in high-performance fuel and lubricant formulations.
• Laboratory & Research: Used as a standard or reagent in analytical chemistry and research applications.
• Agrochemical Carrier: Functions as a solvent or carrier in pesticide and herbicide formulations.

Quality Control

Our Decahydronaphthalene is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practices (cGMP) where applicable. Every lot is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, isomer ratio (cis/trans), water content, and impurity profiles. We ensure compliance with REACH regulations for global market access.

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. Keep container tightly sealed when not in use to prevent moisture absorption and evaporation.
