Description

CAS: 5538-51-2 | C9H7ClO3 | 198.602 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
