What is Aldehyde?
Aldehydes are organic compounds containing a carbonyl group (C=O) bonded to at least one hydrogen atom, giving the characteristic –CHO functional group at the end of a carbon chain. Aldehydes are named with the suffix -al (e.g., methanal, ethanal). They are intermediate in oxidation state between alcohols and carboxylic acids.

Manufacture of resins, plastics, and dyes (formaldehyde, acetaldehyde); flavouring agents and perfumes; chemical intermediates in synthesis; preservatives (formaldehyde solution/formalin); vanillin (food flavour); glutaraldehyde as disinfectant
Many aldehydes are toxic and irritating — formaldehyde is a known human carcinogen (IARC Group 1) and strong sensitiser. Acetaldehyde is flammable and suspected carcinogen. Use in well-ventilated areas or fume hood. Wear appropriate PPE. Store away from oxidisers.
