Bromochloro-5,5-dimethylhydantoin  (Synonyms: BCDMH)

Bromochloro-5,5-dimethylhydantoin (BCDMH) is a fungicide. Bromochloro-5,5-dimethylhydantoin disrupts bacterial cell membranes, alters membrane structure and permeability, and induces leakage of soluble proteins and ions. Bromochloro-5,5-dimethylhydantoin is applicable to studies related to bacterial infections^[1].

Bromochloro-5,5-dimethylhydantoin (5-25 mg/L; 3 min) induces potent bactericidal activity against Escherichia coli 8099, resulting in 6.56 and 6.99 log₁₀ reductions in viable counts after 3 min of exposure at 20 mg/L and 25 mg/L respectively, while lower concentrations induce less or no bactericidal effect^[1].
Bromochloro-5,5-dimethylhydantoin (20 mg/L; 3 min) induces elongation of Escherichia coli 8099 cells, suggesting an SOS response, while causing less visible membrane surface damage compared to other treatments^[1].
Bromochloro-5,5-dimethylhydantoin (20 mg/L; 1-20 min post-exposure) induces minimal leakage of potassium and magnesium ions from Escherichia coli 8099 cells, with ion leakage remaining near baseline levels over 20 min of exposure^[1].
