Formula Weight: 781.50

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
