Formaldehyde
Known for its preservative and adhesive properties.
Formalin
An aqueous solution of formaldehyde that is 37 percent by weight, usually also containing 10 to 15 percent methanol to prevent polymerization of the formaldehyde.
Formaldehyde
Formaldehyde ( (listen) fer-mal-duh-hahyd, also (listen) for-) (systematic name methanal) is a naturally occurring organic compound with the formula CH2O (H−CHO). The pure compound is a pungent-smelling colorless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous solution (formalin).
Formalin
A solution of formaldehyde in water; used as a disinfectant and to preserve biological specimens.
Formaldehyde
A pungent colorless flammable gaseous compound, CH2O, the simplest and most reactive aldehyde, used for manufacturing melamine and phenolic resins, fertilizers, dyes, and embalming fluids and in aqueous solution as a preservative and disinfectant.
Formalin
An aqueous solution of formaldehyde, used as a preservative in museums and as a disinfectant.
Formaldehyde
(organic compound) The simplest aldehyde, HCHO, a colourless gas that has many industrial applications; it dissolves in water to give formol (10%) and formalin.
Formalin
A 10% solution of formaldehyde in water; used as a disinfectant or to preserve biological specimens
Formaldehyde
A colorless, volatile liquid, H2CO, resembling acetic or ethyl aldehyde, and chemically intermediate between methyl alcohol and formic acid.
Formaldehyde
A colorless poisonous gas; made by the oxidation of methanol
