Commentaires

L'ortho-phtalaldéhyde pur est rarement rencontré dans le milieu de travail. Lorsqu'il est utilisé comme désinfectant, il se présente sous forme de solution aqueuse dont la concentration est d'environ 0,55 %. Les solutions commerciales contiennent des additifs qui permettent d'en stabiliser le pH, tels que l'acide citrique et les phosphates, des agents de conservation et des colorants.

L'ortho-phtalaldéhyde est surtout utilisé comme désinfectant chimique à haute efficacité pour des instruments dentaires ou médicaux, comme les endoscopes. Il est souvent considéré comme une alternative plus sécuritaire au glutaraldéhyde.

Il est également employé en laboratoire, comme réactif pour les analyses fluorométriques d'amines primaires et de thiols.
