ACTIVITY

 

The N -1386 structure is biologically active as are its breakdown products. It is most reactive in a pH range of
6.5 to 7.5, but because of the slow rate of hydrolysis, it remains effective at higher pH’s as well.

 

Useful pH Range: Half-life at pH @ 36 ° C

STABILITY

 

N-1386 is stable at ambient conditions. It will slowly decompose above 100 - 140 °C. It is not shock sensitive and
does not form unstable peroxides or polymers.

 

SOLUBILITY

 

The solubility of N-1386 in water is 70 ppm; in ethylene glycol (25 °C), 6.2 + .1% by weight.

 

AVAILABILITY

 

N-1386 is available in commercial quantities as technical grade 98% pure, as a 35% solution in hexylene glycol,
as a 40% naphtha solution.
