2-Bromo-2-nitro-1,3-propanediol (Bronopol, BNP)

2-Bromo-2-nitro-1,3-propanediol (Bronopol, BNP) CAS No.52-51-7 Specification: BP2007 High Content, High Effeciency

2-Bromo-2-nitro-1,3-propanediol (Bronopol, BNP) is a highly active antimicrobial chemical compound whose chemical formula is 2-bromo-2-nitropropane-1,3-diol. Bronopol's low mammalian toxicity (at in-use levels) and exceptional activity against bacteria (especially the troublesome Gram-negative species) ensured that it became popular as a preservative in many consumer products such as shampoos and cosmetics. Bronopol was subsequently taken up as an effective antimicrobial in many industrial environments such as paper mills, oil exploration and production facilities, as well as cooling water disinfection plants.
