Thermo Scientific™ Acetaldehyde 99.5%, Extra Pure

Acetaldehyde (ethanal) is a volatile, highly reactive aldehyde widely used in organic synthesis, chemical manufacturing, and analytical chemistry. This Thermo Fisher Scientific grade offers a purity of 99.5% (GC), making it suitable for high-purity synthesis, research, and industrial laboratory use.

Supplied as a clear, colorless liquid, acetaldehyde has a low boiling point (21 °C) and very low flash point (–27 °C), requiring strict safety and refrigeration handling. It is particularly useful in producing acetic acid, pyridine derivatives, resins, solvents, and as an intermediate in the manufacture of fragrances, flavors, and pharmaceutical compounds.
