Formula: C21H27N7O17P3.K
UV Spectral Analysis:
Ratios at pH 7.5
A250/A260 (0.83 ± 0.03)
A280/A260 (0.21 ± 0.02)
ε at 260 nm (18.0 ± 0.5) x 103
Ratios at pH 10 after reduction with G6PDH*
A340/A260 (0.43 ± 0.02)
ε at 340 nm (6.2 ± 0.2) x 103
Purity:
Determined by increase in absorbance at 340nm on enzymatic reduction with G6PDH* at pH 10 (More than 95%)
*G6PDH = Glucose-6-phosphate dehydrogenase(yeast) (EC 1.1.1.49.)
Potassium Content: 0% by flame photometyl
Water Content: < 8% by Karl Fischer
Condition for Storage:
Keep tightly stoppered in the dark below 5 °C.
Moisture will reduce the purity.
For prolonged storage, keep below -20 °C.
Shipping condition: Refrigerate
