For chemists and product developers, a deep understanding of chemical intermediates is fundamental to innovation. 2-(Methylthio)ethanol (CAS 5271-38-5), a chemical compound with a unique sulfur-containing structure, serves as an excellent case study in understanding synthesis, properties, and applications. As a seasoned chemical manufacturer, we appreciate the intricate chemistry that makes such intermediates valuable across various industries.

Chemical Synthesis Pathways

The synthesis of 2-(Methylthio)ethanol typically involves the reaction between methyl mercaptan (CH3SH) and 2-chloroethanol (ClCH2CH2OH) under alkaline conditions. This nucleophilic substitution reaction replaces the chlorine atom with the methylthio group, yielding the desired product. Other methods may involve the reaction of sodium thiomethoxide with 2-chloroethanol or ethylene oxide with methyl mercaptan. Understanding these synthesis routes is crucial for manufacturers to ensure purity, optimize yield, and control production costs. When you buy 2-(Methylthio)ethanol, the efficiency and methodology of its production by the manufacturer directly impact its quality and cost.

Key Chemical and Physical Properties

2-(Methylthio)ethanol (Molecular Formula: C3H8OS, Molecular Weight: 92.16) is typically presented as a clear, colorless liquid. Key physical properties include:

  • Boiling Point: Approximately 169-171 °C, indicating its relatively low volatility at room temperature.
  • Density: Around 1.06 g/mL at 25 °C.
  • Refractive Index: Typically around 1.4930 at 20 °C.
  • Flash Point: Approximately 70 °C (158 °F), classifying it as a combustible liquid.
  • Solubility: While not miscible with water, it is soluble in many organic solvents.
  • Odor: Possesses a distinct, potent, sulfurous, and meaty aroma, noticeable even at very low concentrations (0.10% in propylene glycol).

Its chemical reactivity stems from both the hydroxyl (-OH) group and the thioether (-SCH3) linkage, allowing it to participate in esterification, etherification, and oxidation reactions, among others. This versatility makes it a valuable intermediate for chemists engaged in complex organic synthesis.

Sourcing Quality 2-(Methylthio)ethanol

For procurement professionals, understanding these chemical characteristics is vital when evaluating a 2-(Methylthio)ethanol supplier. Ensuring the manufacturer adheres to strict quality control during synthesis guarantees the purity and consistency of the product. When inquiring about the price of 2-(Methylthio)ethanol, consider the supplier's expertise in chemical manufacturing and their ability to provide detailed technical data. Partnering with a reliable 2-(Methylthio)ethanol supplier, especially one with a strong presence in regions like China, can offer both quality assurance and competitive value.

By appreciating the synthesis and properties of 2-(Methylthio)ethanol, industries can better leverage its potential as a fundamental building block in chemical innovation.
