Used as a reagent in organic synthesis, particularly for the preparation of hydrazides and hydrazones. It serves as a protecting group for carbonyl compounds, enabling selective reactions in complex molecules. Applied in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals. Also utilized in the development of polymer materials and as an intermediate in the production of active pharmaceutical ingredients (APIs). Its role in forming stable derivatives makes it valuable in analytical chemistry for identifying and quantifying carbonyl-containing compounds.
