Product Description

Product Description

Basic Information

• Product Name: (S)-(-)-2-Methyl-1-butanol; (S)-2-Methylbutan-1-ol
• CAS Number: 1565-80-6
• Molecular Formula: C5H12O
• Molecular Weight: 88.15 g/mol

Physical and Chemical Properties

• Appearance: Colorless transparent liquid with a mild alcoholic odor.
• Optical Activity: [α]n20 = -11.9° (c=1, ethanol). It exhibits levorotation due to the chiral carbon atom at the 2nd position.
• Density: 0.819 g/mL at 25°C
• Boiling Point: 128-132°C (at atmospheric pressure)
• Melting Point: -117°C
• Solubility: Highly soluble in organic solvents like ethanol, diethyl ether, and acetone; partially miscible with water (approximately 9 g/100 mL at 20°C).
• Chemical Properties: As a primary alcohol, it undergoes reactions such as esterification, oxidation (to form aldehydes or carboxylic acids), halogenation, and dehydration. The chiral carbon enables stereoselectivity in asymmetric synthesis.

Application Fields

• Chiral Synthesis Intermediate:
  Used in the preparation of chiral compounds for pesticides, pharmaceuticals, etc., such as intermediates for insect pheromones, antibiotics, or hormonal drugs, controlling the configuration of reaction products through chiral induction.
• Fragrance and Flavor:
  Due to its mild alcoholic aroma, it serves as a food additive (e.g., in beverages, candies) or a component in daily chemical fragrances, and can be used to formulate fruity or herbal scents.
• Solvent and Organic Synthesis:
  Acts as a medium-polarity solvent for coatings, inks, or organic reaction media; participates in the preparation of chiral esters, ethers, and other derivatives.
• Analytical Chemistry:
  Serves as a chiral standard for chiral separation analysis in gas chromatography (GC) or high-performance liquid chromatography (HPLC), or as a reference for optical rotation.

Safety and Storage

• Hazards:
  • Flammable; vapor forms explosive mixtures with air (explosion limit 1.4%-9.0% vol). Combustible when exposed to open flames or high heat.
  • Causes mild irritation to skin and eyes; inhaling high concentrations may irritate the respiratory tract.
• Safety Measures:
  • Operate in a well-ventilated area, avoid contact with open flames, and wear protective gloves and goggles.
  • Store in a cool, dry place, away from oxidants and fire sources; seal containers to prevent volatilization.
• Hazard Symbols: Xi (Irritant), F (Flammable)

Typical Application Examples

• As an intermediate in pesticide synthesis for preparing chiral insecticides, enhancing efficacy and reducing environmental impact;
• As a precursor of chiral ligands in asymmetric catalytic reactions, regulating the stereoselectivity of metal catalysts.
