#chemical compounds
- Aldehyde — An organic compound containing a carbonyl functional group bonded to a hydrogen atom (the formyl group, -CHO), necessarily located at the end of a carbon chain. Aldehydes are obtained industrially or in the laboratory through the dehydrogenation or controlled oxidation of primary alcohols and are widely used in chemical synthesis, the perfume industry, and disinfectant production.
- Aldol — A bifunctional organic compound containing both an aldehyde group (-CHO) and a hydroxyl group (-OH) attached to a carbon atom in the beta position (b-hydroxyaldehyde). The term specifically designates 3-hydroxybutanal, obtained via the aldol condensation of two acetaldehyde molecules, serving as a critical intermediate in the industrial synthesis of butadiene and other macromorphological compounds.
- Azurite — A natural basic copper carbonate mineral with a monoclinic crystal structure, characterized by an intense, glossy, vitreous blue color and a famous chemical instability, often transforming into malachite under the influence of moisture. This structural mineral is found in the oxidation zones of copper ore deposits, historically used as a fine paint pigment and currently as a semi-precious stone for jewelry or decorative objects.
