These aren't one chemical, so there isn't one set of properties. But the top sellers fall into a few families, and each family behaves its own way. Knowing which one you're buying makes storage, handling and ordering a lot easier.
Alcohols and solvents. Ethanol, isopropyl alcohol, acetone, heptane and toluene are flammable liquids that evaporate quickly. Ethanol 200 proof, for example, has a flash point of 14.0°C (57.2°F), so its vapors can ignite below normal room temperature if a flame or spark is nearby. Flammable liquids ship as hazmat, and a hazmat fee can apply. Keep them tightly closed, cool and away from heat.
Oxidizers. Hydrogen peroxide and sodium hypochlorite react with whatever they touch, and they lose strength as they age. Hydrogen peroxide breaks down into water and oxygen. Sodium hypochlorite weakens with heat and light, and you should never mix it with acids or ammonia, because that releases toxic gas.
Strong acids. Nitric, sulfuric and hydrochloric acid, along with trichloroacetic acid at 85%, are corrosive. Wear gloves and eye protection, and check the Chemical Storage Compatibility Chart before you shelve one next to anything else.
