DPTA NONOateNitric oxide (NO) donor. The half-life time is 5 hours at 22°C in 0.1M phosphate buffer, pH 7.4. Decomposition of NONOates is nearly instantaneous at pH 5.0.Product SpecificationAlternative Name: Dipropylenetriamine NONOateFormula: C6H17N5O2 MW: 191.2 CAS: 146724-95-0 Purity: ≥98% Appearance: White to off-white crystalline solid. Hazard: IRRITANT. Solubility: Highly soluble in water. Long Term Storage: -20°C Use/Stability: Crystals are sensitive to moisture and become discolored on exposure to air. Alkaline solutions of NONOates in 0.01M NaOH are stable for 24 hours when stored at 0°C. Concentration of the basic stock solution can be measured by UV if there is uncertainty about the condition under which it was prepared or stored. Handling: Protect from light and moisture.
