Butanol, also known as butyl alcohol, is a type of alcohol with four carbon atoms in its molecular structure. There are four isomeric forms of butanol, which differ based on the location of the hydroxyl (-OH) group on the carbon chain. These isomers are:

1. n-Butanol (1-butanol): The "n" stands for "normal," indicating that the carbon chain is linear. It is often used as a solvent and in the production of plastics, coatings, and pharmaceuticals.
2. Isobutanol (2-methyl-1-propanol): This isomer has a branched structure, with a methyl group (-CH3) attached to the second carbon atom. Isobutanol has applications as a solvent, in the production of various chemicals, and as a fuel additive.
3. Sec-butanol (2-butanol): It has a branched structure, with the hydroxyl group attached to the second carbon atom. It's used as a solvent and in the manufacture of perfumes and pharmaceuticals.
4. Tert-butanol (2-methyl-2-propanol): This isomer is highly branched, with the hydroxyl group attached to a carbon atom that is itself attached to three other carbon atoms. Tert-butanol is used primarily as a solvent and as a chemical intermediate.

Ethylene glycol monoethyl is a chemical compound that belongs to the family of glycol ethers. It is also known by its systematic name, 2-ethoxyethanol. Its chemical formula is C4H10O2, and its molecular weight is 90.12 g/mol. Ethylene glycol monoethyl is a clear, colorless, and slightly viscous liquid with a faint, sweet odor. It is commonly used as a solvent in various industrial applications, such as in the manufacturing of paints, varnishes, and lacquers, as well as in the production of cleaning agents and cosmetics. However, it is important to note that ethylene glycol monoethyl can be toxic if ingested or inhaled in large amounts. It can cause irritation to the eyes, skin, and respiratory system, and prolonged exposure can lead to more serious health effects. Therefore, it is crucial to handle and store this chemical compound safely and to follow proper safety precautions when working with it.

Trimethylpentane, also known as isooctane, is a high-purity hydrocarbon solvent commonly used in High-Performance Liquid Chromatography (HPLC) as a reference standard or mobile phase component. It is often utilized in chromatography due to its low polarity and high purity, which ensures accurate and reproducible results. HPLC-grade trimethylpentane is purified to meet stringent quality standards, minimizing impurities that could interfere with analytical measurements. It's crucial for ensuring precise and reliable chromatographic separations in analytical laboratories.
