Import Bronopol — Buy in Bulk from Supplier in China

Bronopol from Haina Industry Co., Ltd. is a broad-spectrum biocide supplied as a tasteless, white or light yellow crystalline powder with the molecular formula C3H6BrNO4 and CAS number 52-51-7. This preservative is effective against bacteria, fungi, and algae, making it suitable for industrial applications where microbial control is critical. Its chemical stability allows for use in systems with pH ranges from 3 to 9, though performance may vary outside this window.

The active compound is 2-bromo-2-nitropropane-1,3-diol, a halohydrin that releases formaldehyde in aqueous solutions, providing its antimicrobial action. Standard industry grades typically achieve a minimum assay of 98.0%, with moisture content below 0.5% and heavy metals limited to 10 ppm for most industrial uses. Bronopol is soluble in water up to approximately 250 g/L at 25°C, a typical value for this class of preservatives, and decomposes at temperatures above 130°C, releasing nitrogen oxides and bromine.

Industrial buyers source Bronopol for use in circulating water systems, paper pulp, paints, plastics, and timber-cooling processes to prevent spoilage and microbial growth. It is also employed in cosmetics and personal care products as a preservative at concentrations up to 0.1%, subject to regional regulatory limits. For bulk import, confirm packaging options such as 25 kg fibre drums with inner plastic bags, which is standard for this product category, and verify compatibility with intended applications.
