2-Methylbutane, also known as isopentane, is a high-purity hydrocarbon solvent with a purity of ≥99.0%. It is widely used in cryogenic freezing, histological tissue embedding, and organic synthesis due to its extremely low melting point (–160 °C) and volatility. This AnalaR NORMAPUR® grade is ideal for applications requiring low contamination levels and is certified free of DNase, RNase, and protease.
Key Features
- High Purity (≥99.0%): Suitable for analytical chemistry and cryogenic applications
- AnalaR NORMAPUR® Grade: Ensures high batch-to-batch consistency for critical lab protocols
- Low Melting Point (–160 °C): Ideal for tissue freezing and snap-freezing in histology or cryobiology
- Certified Free from DNase, RNase, and Protease: Minimizes risk of nucleic acid/protein degradation
- Low Water Content (≤0.5%): Supports stability in moisture-sensitive reactions
- Glass Bottle Packaging: Ensures purity and chemical compatibility
