cas no.: 10222-01-2
struction:
content: ≥99%
property:
white crystal. melting point 125 °c, soluble in general organic solvents such as acetone, benzene, dmf, ethanol, polyethylene glycol (peg), etc.), slightly soluble in water at (25 °c, 100 g water dissolved 1.5 g). in its aqueous solution under acid condition is relatively stable, easy to hydrolysis under alkaline conditions. improve the ph value, heating, using ultraviolet light or fluorescent light, can make its dissolution accelerated dramatically. easy by reducing agent, such as hydrogen sulfide debromination into non-toxic cyanoacetic acid amine, the sterilization rate is reduced greatly. the ph from 6.7 to 9.7, the half-life is from 37.0 h to 0.11 h.
