The "Technical Specification for Disinfection of Medical Institutions" requires that phthalaldehyde should be sealed, protected from light, and stored in a cool, dry and ventilated environment. How long is the validity period after opening? There is no relevant regulation at present, in view of the excellent stability of OPA in a wide pH range (pH 3~9). Therefore, it can be used within the validity period of the product label after opening. It is also possible to conduct research on the validity period after the OPA is opened to explore more scientifically credible results. From a management point of view, it is more important to pay attention to the standardized storage and use after opening to ensure the disinfection effect.
