2-Methoxy-1-Propanol is an organic compound widely used in industry as a solvent and chemical intermediate. The molecular formula is C4H10O2. This chemical has a CAS number of 1589-47-5 and an HS Code of 29094990. It appears as a clear, colorless liquid with a faint, ether-like scent. Industrial users value its balance of hydrophilic and hydrophobic properties. This makes 2-Methoxy-1-Propanol adaptable across coatings, printing inks, cleaners, and electronics manufacturing.
Its molecular structure consists of a three-carbon backbone with a methoxy group (-OCH3) attached to the second carbon and a hydroxyl group (-OH) on the first carbon. This combination produces a compound with both alcohol and ether functional groups, which contributes to its versatility. The molecular weight stands at 90.12 g/mol, a specific detail that allows for easy calculation in mixing and formulation. Density measures around 0.924 g/cm³ at 20°C, making it less dense than water but dense enough for handling without excess volatility.
The product lives most of its working life as a liquid at room temperature due to its melting point at -96°C and boiling point at 120-125°C. Rarely, it may be encountered as a vapor given its relatively low vapor pressure. Commercial supply arrives in drums, containers, or bulk tanks, in clear liquid form. No commercial grades appear as crystals, flakes, solid powders, or pearls. Solubility in water is high—above 500 g/L at 20°C—so mixing with aqueous or polar systems happens smoothly. The refractive index comes in at around 1.412, and the flash point reaches approximately 38°C. Standard storage practices suggest keeping it in steel or lined drums under shade, away from sources of intense heat or ignition.
Because of its chemical makeup, 2-Methoxy-1-Propanol fits into a long list of industrial jobs. Printers and paint manufacturers add it to water-based inks or coatings to support pigment dispersion and ensure proper drying. Its solvent power bridges water and organic phases, allowing for effective cleaning of hard-to-remove residues on electronic circuit boards and polished surfaces. Cleanroom environments use it during device fabrication, since it leaves behind minimal residue and does not interfere with sensitive processes. Workers handling adhesives or cleaners appreciate how this solvent helps modify evaporation rates and viscosity. In chemical synthesis, it works as both a reactant and a process solvent, helping to solubilize both organic and inorganic substances through its dual alcohol-ether structure.
People who spend time with 2-Methoxy-1-Propanol need to know it brings health risks. While the scent remains mild, vapor inhalation can cause dizziness, headache, or even central nervous system effects in high concentrations. Accidental contact with skin can dry and irritate tissues, and eye exposure causes significant discomfort. The chemical falls into the flammable liquid category due to its flash point, so static discharge or leaks near exposed flames create fire hazards. Local exhaust ventilation, grounded containers, and proper flame arrestors become critical in busy production environments. In case of spills, absorbent material can contain liquid, but direct skin contact must be avoided. Disposal always needs to follow regional hazardous waste rules. Use of gloves, goggles, and respirators in poorly ventilated areas helps cut accident risks.
Chemical spills or leaks into water sources affect aquatic life for long periods because the compound does not break down quickly. Wastewater treatment methods succeed best when combined with physical removal and advanced oxidation processes. Proper labeling and transport lessen chances of accidental or illegal dumping. Companies often provide Safety Data Sheets that detail safe handling, storage instructions, and emergency response for both small laboratories and large-scale chemical plants. Training workers in the use of personal protective equipment and clear emergency procedures supports not only their health and safety but also the natural environment outside the factory gates.
Keeping up with cleaner production standards, 2-Methoxy-1-Propanol brings industrial users a bridge between performance and readiness for regulatory compliance. Its ability to dissolve challenging resins and dyes—plus miscibility with water—means fewer process changes need to happen when companies move away from harsher chemicals. Technicians find it easier to switch between different formulas because one solvent can manage cleaning, thinning, and formulation tasks depending on concentration. Research keeps looking for ways to substitute less hazardous ingredients without losing function, but demand for this raw material stays steady thanks to reliability and broad chemical compatibility.
The industry faces a growing push to reduce hazardous chemical footprint and improve workplace safety. This push opens up opportunities for engineering controls such as improved ventilation, closed transfer systems, and onsite solvent recovery. Process automation and remote handling gear can further limit exposure while helping to capture and recycle more solvent. Chemists look at designing new molecules that offer the same mix of volatility, solvency, and water compatibility from less hazardous starting materials. Educators, plant managers, and health officers work together to keep safety training up-to-date and to enforce a culture of reporting near-misses. Existing regulations, such as those governing chemical storage and worker exposure, must be enforced on a daily basis, with clear records and retraining as processes change or expand. These moves protect workers, neighborhoods, and the environment—all anchored by a focus on practical, responsible use of robust industrial compounds like 2-Methoxy-1-Propanol.
