N,O-Dimethylhydroxylamine hydrochloride (C2H8ClNO) is a white crystalline solid used in organic synthesis, especially for preparing Weinreb amides. These amides react with organometallic reagents to form ketones or aldehydes selectively. The compound is stable as a hydrochloride salt and is soluble in water and polar solvents. It should be handled with care, as it can irritate skin, eyes, and the respiratory system. Store in a cool, dry place.
