Anwendungen

O-Acetylsalicyloyl chloride was used in the synthesis of enantiomerically pure bidentate heteroorganic ligands built on simple achiral skeletons and containing an aziridine moiety. It was used in the general synthesis of acetoxybenzamides. It was used in the chemical synthesis of 2,2,6,6-tetramethyl-1-piperidinyloxy(TEMPO)-aspirin conjugate via condensation reaction with 4-hydroxy-TEMPO. It was used as reagent in acylation of cyclobutenediones.

Bemerkungen

Moisture Sensitive. Store under dry inert gas. Store away from strong bases.
