2-(2-Chloroethoxy)Ethanol is a chemical raw material widely used in organic synthesis, pharmaceuticals, and agrochemical manufacturing. This compound features a clear, colorless liquid form at room temperature, carrying a faint, sweet odor that reminds users of similar ethylene glycol ethers. Molecularly, it has the formula C4H9ClO2, with a structural layout that shows an ethoxy group bonded to a chloroethyl chain. People working with this material will notice its solubility in water and many organic solvents, making it effective for a range of chemical processes. Known by its HS Code 29094990, it finds a spot in customs and international trade for specialty organics. With a molecular weight around 124.57 g/mol, it is recognized among chemists as a niche but essential piece in the synthetic chemistry puzzle.
The presence of both ether and hydroxyl functional groups in 2-(2-Chloroethoxy)Ethanol gives this chemical a dual personality in terms of reactivity. The hydroxyl portion brings in hydrophilic qualities, while the chloroether chain introduces reactivity that synthetic chemists depend on for introducing chlorine moieties into more complex organic molecules. Its density clocks in at around 1.13 g/cm3, and the boiling point falls near 188°C, which puts it in the range of other glycol ethers. Over the years, I’ve handled similar substances and always found their volatility to require vigilant handling. With its clear liquid nature, it is tempting to overlook the risks, but staying grounded in the basics—like always labeling and storing it away from acids, bases, and oxidizers—remains key. Its flash point sits just above room temperature, so open flames must stay far away.
2-(2-Chloroethoxy)Ethanol mostly appears as a liquid, though in colder conditions or high-purity samples, the material can form crystalline solids or flakes. On the rare occasion a supplier sends a bottle during winter, small crystals sometimes gather at the bottom. Bulk shipments usually arrive in drums or jerry cans, always tightly sealed since even minor leaks release vapors you won't want to breathe in. Safety-wise, this compound qualifies as hazardous. Every bottle and drum comes with hazard labels for good reason—skin or eye contact triggers irritation, and inhaling the fumes invites headaches or worse. Long sleeves, gloves, goggles, and a proper fume hood become routine parts of the workday whenever I need to measure or decant it.
On paper, specifications for 2-(2-Chloroethoxy)Ethanol usually include purity percentages over 98%, with close monitoring of water content and related impurities. The HS Code 29094990 links it to the broader category of ether-alcohol derivatives, making customs clearance and trade paperwork predictable for seasoned buyers. Documented density and refractive index give users clues about the batch's authenticity and quality. Every time I check a certificate of analysis, I look for the characteristic boiling point and density values—any odd numbers suggest improper storage or a mixed-up shipment. In most chemical plants and labs, this level of diligence keeps production safe and predictable.
Calling this material hazardous is not just a warning label—short or prolonged exposure leads to real health risks. Skin absorption, eye contact, and inhalation all pose threats, from mild rashes to more severe symptoms like respiratory distress. Over time, repeated exposure can offer silent, cumulative damage. In my experience, folks new to industrial chemicals sometimes get careless, especially with a substance that doesn’t carry an obvious, pungent smell or bright color. I always train teams to focus on containment and ventilation, not just for themselves but for the wider workspace. Detailed labeling, solid wall storage, and easy access to safety data sheets keep accidents rare.
The hazards surrounding 2-(2-Chloroethoxy)Ethanol require not just basic care but an ongoing commitment to best practices. Transitioning from open buckets or basic glassware to enclosed transfer systems cuts exposure sharply. Investing in chemical fume hoods or exhaust systems reduces inhalation risks. Strict training—both for new and experienced staff—keeps awareness sharp. Regulatory requirements like REACH registration and proper waste handling protocols guide safe disposal, usually through high-temperature incineration or specialization chemical waste handlers. For those interested in greener chemistry, alternatives or controlled use in closed loops could minimize environmental footprints, but that depends on process flexibility and budget.
This chemical helps unlock more complex synthetic routes in pharmaceuticals, agrochemicals, and specialty polymers. Getting the material at high purity makes the difference between a successful batch and wasted raw materials. Downstream products—whether they’re disease-fighting drugs or specialty coatings—depend on reliable handling of every bottle or drum that comes into the plant. Years of lab work taught me that no substitute exists for clear, accurate specifications, reliable suppliers, and teamwork when safety is on the line. Product descriptions and safety data must back up every purchase and every use, directly supporting quality control.
