For research and development scientists, the precise selection of chemical reagents and intermediates is fundamental to experimental success. 3-Methyl-2-Butanol (CAS 598-75-4), a secondary alcohol with a unique branched structure, presents itself as a valuable compound for a multitude of laboratory applications, ranging from organic synthesis to specialized solvent use. Understanding its chemical characteristics and how to source it effectively is paramount for R&D professionals.

Chemical Properties and Reactivity Profile

3-Methyl-2-Butanol, often abbreviated as 3M2B or referred to by its common name sec-isoamyl alcohol, possesses the molecular formula C5H12O. It is a clear, colorless liquid at standard temperatures, characterized by its distinct, somewhat pungent odor. Its physical properties, such as a boiling point around 113.6 °C and a flash point of 26.7 °C, indicate moderate volatility and flammability, necessitating appropriate handling precautions in a laboratory setting.

From a chemical perspective, the hydroxyl group on the secondary carbon atom makes 3-Methyl-2-Butanol a reactive molecule. It readily undergoes typical alcohol reactions, including esterification, oxidation, dehydration, and etherification. This reactivity profile makes it an excellent starting material or intermediate in various organic synthesis pathways. Researchers often employ it in the development of novel compounds, pharmaceuticals, and fine chemicals where specific stereochemistry or branching is desired.

Sourcing for Research: Purity and Availability

When sourcing 3-Methyl-2-Butanol for R&D purposes, the emphasis is often on obtaining a high-purity product. While industrial grades might suffice for some applications, research endeavors typically demand purities of 98% or higher, often verified by Gas Chromatography (GC). Ensuring the absence of isomeric impurities or residual solvents is critical for reproducible experimental results. Scientists often search for suppliers who can provide small to moderate quantities, with detailed analytical data available.

For R&D scientists and procurement specialists in research institutions, the process to buy 3-Methyl-2-Butanol involves identifying reliable chemical suppliers. Companies that specialize in laboratory chemicals are often good starting points. When evaluating suppliers, consider:

  • Purity and Analysis: Ensure that the supplier provides a clear Certificate of Analysis (CoA) with reliable purity data.
  • Quantity Flexibility: Look for suppliers who can accommodate smaller research-scale quantities, rather than just bulk industrial orders.
  • Lead Times: Research-specific projects often have tight timelines, so prompt delivery is crucial.
  • Reputation: Trustworthy suppliers have established reputations for quality and service within the scientific community.

Requesting a quotation for the required quantity is standard procedure. While cost is always a factor, for research, the integrity of the chemical and the reliability of the supplier often take precedence over marginal price differences.

In summary, 3-Methyl-2-Butanol (CAS 598-75-4) is a valuable asset for R&D scientists due to its reactivity and versatile applications in organic synthesis. By focusing on high purity and partnering with dependable chemical suppliers, researchers can ensure they have the quality materials needed to drive innovation and achieve their experimental objectives.
