1-Propanol, 1-chloro-2-methyl-, propanoate is an organic chemical that brings together properties familiar to both esters and halogenated hydrocarbons. Its structure shows a propanoate ester linked with a chloro-substituted propanol backbone, giving it a certain versatility for industrial applications. Over the years, chemists have come to respect compounds that combine halogen and ester function groups, not just for unique reactivity but for the kinds of tailored properties needed in specialty syntheses.
With the formula C7H13ClO2, this substance features an ester bond between a chlorinated, methylated propanol and a propanoic acid residue. The presence of a chlorine atom at the 1-position on the propanol branch along with a methyl group at the 2-position changes both the reactivity and physical performance compared to its non-chlorinated cousins. The arrangement adds a layer of polarity, affecting how it interacts in solution or reacts with other chemicals, which sparks plenty of interest in both expert chemical labs and industrial processing facilities.
I've observed that chlorinated esters like this one usually come as a clear to slightly yellowish liquid at room temperature, although it's possible to encounter solid or crystalline forms if the product is especially pure and cool. Given its structure, expect a density range of about 1.1 to 1.2 grams per cubic centimeter. Solubility remains modest in water—typical for medium-chain esters—but strong affinity for organic solvents, from toluene to ether, opens doors to diverse applications: coatings, adhesives, or intermediate steps in synthesis. Whether in flakes, powder, crystal, or liquid, this chemical often arrives in tightly sealed containers, with a pungent, sharp odor hinting at its halogenated backbone.
International shipping and trade require tracking this compound under a specific Harmonized System Code—usually found under groupings for organic chemicals with chloro substituents or specific esters. That may put it in the 2915 or 2903 HS code families, depending on distinctions between acids, esters, and halogen derivatives. Anyone moving this chemical across borders has to keep up with customs declarations, and it's worth noting that any misuse or spillage must be logged due to its classification as a hazardous substance under GHS for both its volatility and chlorine content. Labelling and paperwork aren’t just bureaucracy; they’re about keeping handlers safer and making supply chains more trustworthy.
Safe storage boils down to keeping temperature and humidity in check. As a substance with halogen groups, 1-propanol, 1-chloro-2-methyl-, propanoate puts containers to the test—metal lids corrode faster, and plastic liners sometimes fail if not made from resistant polymers like PTFE. Handling in powder or solid state ups the ante on personal protection equipment, since inhalation and splash risks aren’t out of the question. Most batches ship as a liquid, but don’t be surprised to run into pearls or solidified chunks if atmospheric conditions get cooler. A lesson picked up after years in chemicals: even a tiny shift in humidity or temperature in the warehouse can change how esters like this behave, from density to solubility.
Describing this compound as hazardous isn’t an exaggeration. The chloro group signals to health and safety teams that inhaling or skin contact can irritate or harm, mainly through solvent activity and possible organ toxicity. Workers exposed without gloves or goggles can face respiratory issues or skin rashes. Spilled material on the floor gets slippery fast—risking both chemical burns and falls. Vapors build up if ventilation lags behind, calling for routine air monitoring to keep below safe exposure levels. Precautions like chemical fume hoods, face shields, and nitrile or neoprene gloves become part of the workday when moving liters at a time.
Making 1-propanol, 1-chloro-2-methyl-, propanoate often starts with 1-chloro-2-methyl-1-propanol (which itself comes from methylation and chlorination steps) and propanoic acid or its activated derivatives. Using established esterification protocols—p-toluenesulfonic acid or sulfuric acid as a catalyst, gentle heat to drive off water, and controlled additions—the compound forms over hours. Purification may call for vacuum distillation and careful attention to avoid side products, especially since residual acid or base can trigger unwanted reactions later on. When you see purity figures upwards of 98%, it means dedicated, hands-on quality control rather than a purely mechanical process.
Lowering harm starts earlier in the supply chain. Using closed systems for synthesis and transfer, companies cut down on vapor exposure and unplanned spills. Building in continuous air quality sensors means leaks don’t go unnoticed until it’s too late. For smaller users or academic labs, switching to pre-diluted solutions slows down how fast vapors fill a room, while integrating waste reclamation makes sure harmful byproducts see proper destruction instead of careless disposal. Training programs show real results—hands-on sessions change habits far better than paperwork. Making the switch to safer containers and secondary containment prevents accidents after years of less-than-ideal storage, and having strict inventory tracking means expired or degraded batches get pulled before they cause trouble.
Chemicals like 1-propanol, 1-chloro-2-methyl-, propanoate play bigger roles than most people notice. Whether in pharmaceutical research, high-performance coatings, or fine chemicals, the blend of chemical reactivity and physical durability gives an edge. Knowing details about density, flake or liquid state, and stability means fewer surprises in process lines and higher yield in syntheses. The right information lets product developers, safety managers, and logistics teams move forward with confidence rather than uncertainty. In my experience, a solid grounding in both molecular structure and real-world hazards means fewer late-night calls and more productive days in the lab or on the production floor.
