NOC-5 is a stable nitric oxide (NO)-amine complex that acts as a NO donor. It can release two equivalents of NO in solution under physiological conditions without a cofactor. [1] The half-life of NOC-5 in PBS (pH 7.4) is 93 minutes at 22°C, and it remains relatively stable in alkaline solution (pH >=10.0). [1]
