Phenylmercuric acetate

Phenylmercuric acetate (CAS 62-38-4), also known commercially as Dyanacide, is an organomercury biocide used across industrial preservation and antimicrobial applications. It delivers broad-spectrum activity against bacteria, fungi, and algae in formulated products and process systems. In coatings, adhesives, and sealants, it functions as an in-can and dry-film preservative, preventing microbial degradation during storage and after application. This ensures the long-term stability and performance of industrial formulations.

Pulp and paper mills have historically used it as a slimicide to control biofilm formation in process water and on equipment surfaces. This application is critical for maintaining efficiency and preventing equipment fouling in high-moisture environments. Textile and leather processing operations apply it to inhibit mold and bacterial growth during wet processing and finished goods storage. It provides essential protection for organic materials susceptible to rapid microbial colonization.

In agriculture, it has been used as a seed treatment fungicide and turf fungicide to protect against soil-borne pathogens. These applications help ensure crop health and maintain the aesthetic quality of professional turfgrass installations. The chemical is supplied as a white to off-white crystalline powder. Technical grade is the standard commercial form, with purity specifications typically at 99% or higher to meet rigorous industrial requirements.

Due to regulatory restrictions on mercury-containing compounds in many jurisdictions, availability is limited. Buyers should confirm compliance with applicable import and use regulations before sourcing this specific organometallic compound.
