We mainly sell aldehydes including formaldehyde, acetaldehyde, and propanal. Aldehyde is an important industrial raw material used in the pharmaceutical and food industries. Aldehydes should be stored in sealed containers, in a cool, dry, well ventilated place, away from ignition sources and flammable materials. In summary, aldehydes are an important class of organic compounds with extensive applications, but safety and protective measures need to be taken when storing and using them.
