Isopropyl Alcohol-IPA, also known as 2-propanol, is a colorless, flammable chemical compound with the molecular formula C3H8O. It is a type of alcohol that is commonly used as a solvent, disinfectant, and cleaning agent in a variety of industries, including healthcare, manufacturing, and electronics. IPA is often used as a disinfectant because it is effective at killing a wide range of microorganisms, including bacteria, viruses, and fungi. It is also commonly used as a solvent for oils, resins, and gums, and as a cleaning agent for electronic devices and other equipment.

Acetaldehyde
- Chemical Structure: Acetaldehyde consists of two carbon atoms, one oxygen atom, and four hydrogen atoms. Its structure is CH3CHO, where the carbon atom in the middle is doubly bonded to an oxygen atom and singly bonded to a hydrogen atom and a methyl group (CH3).
- Occurrence: Acetaldehyde can be found naturally in various ripe fruits, coffee, and heated milk. It is also produced by the oxidation of ethanol (alcohol) by enzymes in the liver and other tissues in humans, making it an intermediate product in alcohol metabolism.
