CAS 1655-42-1: METHYL ISOBUTYL KETONE-DNPH

Description: Methyl isobutyl ketone (MIBK) is an organic compound classified as a ketone, and its derivative, methyl isobutyl ketone-DNPH, is a derivative formed with 2,4-dinitrophenylhydrazine (DNPH), which is commonly used for the qualitative and quantitative analysis of carbonyl compounds. The compound typically appears as a yellow to orange solid when crystallized. MIBK itself is a colorless liquid with a characteristic odor, and it is known for its solvent properties, making it useful in various industrial applications, including paint thinners, coatings, and adhesives. The DNPH derivative is particularly significant in analytical chemistry for the identification of ketones and aldehydes through the formation of stable hydrazones. The compound is moderately soluble in water and highly soluble in organic solvents. Safety considerations include its flammability and potential health effects upon inhalation or skin contact, necessitating appropriate handling and storage measures. Overall, methyl isobutyl ketone-DNPH serves as a valuable tool in chemical analysis and research.
