Formaldehyde is also a precursor to polyfunctional alcohols such as pentaerythritol, which is used to make paints and explosives. Other formaldehyde derivatives include methylene diphenyl diisocyanate, an important component in polyurethane paints and foams, and hexamine, which is used in phenol-formaldehyde resins as well as the explosive RDX.
The Biden administration has officially determined the chemical formaldehyde poses an “unreasonable” risk to human health and should be regulated. The Environmental Protection Agency (EPA ...

Commonly, glutaraldehydes and formaldehyde are used in this process, but in different ways. When using the first type of disinfectant, the instruments are soaked in a 2–4% solution for at least 10 hours while a solution of 8% formaldehyde will sterilize the items in 24 hours or more.
Formaldehyde works to fixate the tissue of the deceased. This is the characteristic that also makes concentrated formaldehyde hazardous when not handled using appropriate personal protective equipment. The carbon atom in formaldehyde, CH 2 O, carries a slight positive charge due to the high electronegativity of the oxygen double bonded with the ...
Available data suggests that mefloquine is safe and effective for use by pregnant women during all trimesters of pregnancy, [24] and it is widely used for this indication. [25] In pregnant women, mefloquine appears to pose minimal risk to the fetus, [ 25 ] [ 26 ] and is not associated with increased risk of birth defects or miscarriages. [ 27 ]
