CPME
Cyclopentyl Methyl Ether
CPME is a hydrophobic ether solvent. Unlike common ether solvents, CPME has high hydrophobicity and low heat of vaporization, enabling processing advantages compared to THF, MTBE, and dioxanes.
Pharmaceutical Synthesis
Used as a solvent for the synthesis, extraction and crystallization of specific components.
Electronics
Cleans precision components to ensure longevity and maintain performance.
Agrochemicals
Used in manufacturing pesticides and herbicides as a solvent for synthesis and extraction.
Formula: C6H12O
Molecular Weight: 100.16 g/mol
Characteristics: High hydrophobicity, wide liquidity range, low heat of vaporization, low peroxide formation, narrow explosion area, stable to acids and bases, easy drying.
CPN
Cyclopentanone
CPN is a high boiling point (bp: 130~131C) five-member ring structure solvent.
Semiconductors
Cyclopentanone has excellent solubility in polyimide, used as a high temperature adhesive.
Electronics Manufacturing
Used as a cleaning solvent in electronic manufacturing equipment to ensure high-performance operation.
Chemical Synthesis
Used as a synthetic raw material for pharmaceutical and fragrance manufacturing.
Formula: C5H8O
Molecular Weight: 84.12 g/mol
Characteristics: High boiling point, stable under standard conditions, versatile solvent with low viscosity, exhibits good solubility for various compounds, key intermediate for industrial chemical synthesis.
