Pharmacology
MeSH Pharmacological Classification
Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed)
Uses & manufacturing
Uses
Used as an antibacterial agent, disinfectant, and veterinary topical antiseptic; [HSDB]
Using Disinfectants or Biocides [Category: Clean]
ANTIBACTERIAL; VET: TOPICAL ANTISEPTIC
Chloramine B used as a disinfectant is inhibitory to Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus.
Methods of ManufacturingPREPD VIA BENZENESULFONAMIDE: CHATTAWAY, J CHEM SOC 87, 145 (1905); CUIBAN ET AL, PHARMAZIE 13, 407 (1958).
General Manufacturing InformationBenzenesulfonamide, N-chloro-, sodium salt (1:1): ACTIVE
Applications
UsesUsed in investigations of the toxicity response of electroactive microbial biofilmsCatalyst for rearrangement of aziridinofullerenes to azafulleroidsOxidizing agent for polymerization of thiophenol, synthesis of o-aminobenzenesulfonic acids and ciproflaxinDecontaminant for mustard
UsesChloramine B's a organochlorine disinfectant, and the effective chloric arrive 26-28%, the property is stable, only loss 0.1% effective chloric after airtight kept 1 year . Slightly soluble in water, and Stimulating & corrosive is small, so the efficacy is slower than hypochlorous acid. Chloramine-B is mainly used for disinfecting container of drinking water, all kind of tableware, fruits and vegetables(5ppm), aquaculture water and enamel instruments(1%). It's also can be used for cleaning breast of cattle, milk cup, livestock urinary tract, festering,etc.
