Also known as: 2,2-Dimethylpropane | Tetramethylmethane
High-purity Neopentane supplied by Dongjian Chemical for specialty solvent, chemical intermediate, blowing agent, analytical standard and fuel-blending applications. Consistent quality, low olefin content, controlled moisture and flexible packaging for laboratory, pilot and industrial use.
Product Applications
Blowing agent for rigid polyurethane and polystyrene foams (excellent expansion efficiency and cell structure control)
Specialty solvent in organic synthesis, electronics cleaning and pharmaceutical processes
Chemical intermediate for fine chemicals and related downstream products
Analytical reference standard for GC, GC-MS and NMR calibration (high symmetry and purity)
Gasoline / aviation fuel blending component (high octane contribution)
Propellant / aerosol component and research chemical
Occasional use as low-temperature working fluid or refrigerant component (R601b related)
Functional Characteristics
Highly branched C5 alkane with a central quaternary carbon
Exceptional chemical stability and low reactivity compared with linear or mono-branched pentanes
Colorless gas at ambient temperature; easily liquefied under moderate pressure or cooling
Low boiling point enables rapid vaporization and precise metering
Non-polar, water-insoluble, fully miscible with most organic solvents
High thermal stability under normal process conditions

Client Collaboration Case
Case 1 – Foam Manufacturer (Southeast Asia)
A rigid PU insulation producer replaced part of their conventional pentane blend with high-purity Neopentane. Result: improved cell uniformity, lower density variation and better thermal conductivity consistency. Dongjian supplied cylinder-to-bulk transition support and on-time monthly deliveries for 18 consecutive months.
Case 2 – Analytical Laboratory Network (Europe)
A multi-site contract testing lab adopted Dongjian Neopentane as GC retention-index reference standard. The material's high symmetry and consistent purity reduced calibration drift and simplified inter-laboratory method transfer.
Case 3 – Specialty Chemical Intermediate User
A fine-chemical company used Neopentane as a low-reactivity process solvent and intermediate carrier. Dongjian provided custom purity specification, moisture control and flexible packaging that matched their pilot-to-commercial scale-up schedule.
Packaging & Supply Options
High-pressure cylinders (various sizes)
Returnable or disposable containers
Bulk / ISO tank supply for larger volumes
Custom labeling and documentation available for different markets
Quality & Documentation
Every shipment is accompanied by Certificate of Analysis, Safety Data Sheet and full shipping documents. Moisture, olefin content and residual impurities are strictly controlled to meet industrial and research requirements.
