Description

trans-1,1,3,4-Tetramethylcyclopentane is a high-purity, highly volatile alicyclic hydrocarbon with a unique, rigid molecular structure. This compound is valued for its role as a specialized intermediate and a high-performance solvent in advanced material synthesis. It is primarily sought by R&D laboratories and industrial manufacturers in the fragrance, pharmaceutical, and specialty chemical sectors for applications requiring precise molecular architecture and controlled volatility.

Application

• Fragrance and Flavor Intermediate: Serves as a key building block for synthesizing musky, woody, or amber odorants due to its stable cyclopentane backbone.
• Pharmaceutical Synthesis: Used as a chiral synthon or a non-polar reaction medium in the development of complex organic molecules and active pharmaceutical ingredients (APIs).
• Specialty Solvent: Acts as a high-performance, low-polarity solvent for coatings, adhesives, and advanced polymer research where rapid evaporation is required.
• Chemical Research & Development: Employed as a standard or reference material in chromatographic analysis and for studying hydrocarbon reactivity and physical properties.
• Lubricant and Fuel Additive Component: Investigated for use in formulating synthetic lubricants or high-octane fuel blends to modify viscosity and combustion characteristics.

Quality Control

Our trans-1,1,3,4-Tetramethylcyclopentane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, specific gravity, and other critical parameters are provided with each shipment to guarantee consistent quality and traceability for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-25°C.
