[Uses]

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.
[Purification Methods]

Check first the IR to see if an OH frequency is present. If so, some free acid is present. Then reflux with acetyl chloride for 2-3hours and fractionate at high vacuum. The distillate should crystallise. It can be recrystallised from hexane or *C6H6 (m 60o, sintering at 52o).
