Methyldibromo glutaronitrile

Methyldibromo glutaronitrile (CAS 35691-65-7 ), commonly referred to as MDBGN, is a broad-spectrum biocide used to control microbial growth in industrial and consumer formulations.

It delivers effective preservation against bacteria, fungi, and yeast at low use concentrations across a range of product types. In water treatment and industrial process fluids, it controls microbial contamination.

This chemical is essential for cooling water systems, paper mill circuits, and metalworking fluids. Coatings, adhesives, and sealant manufacturers incorporate it as an in-can preservative to extend shelf life.

It prevents spoilage during storage and distribution. The textile, leather, and pulp and paper industries rely on it to protect wet-process materials and finished goods from microbial degradation.

It has also been used in personal care formulations as a preservation booster, though regulatory restrictions in cosmetics vary by market and must be verified before sourcing for that application.

MDBGN is available as a solid crystalline powder and in liquid solution blends, often combined with other biocidal actives such as phenoxyethanol for broader-spectrum performance.

The technical grade is the standard supply form for industrial applications. Buyers should confirm regional regulatory status, particularly for cosmetic end uses, prior to procurement.

Approved concentrations differ across jurisdictions. Ensuring compliance with local safety standards is necessary when integrating this biocide into diverse manufacturing processes and product lines.
