Full Name: β-Nicotinamide-Adenine Dinucleotide Phosphate, Reduced (β-NADPH)
CAS No.: 2646-71-16
Formula Weight: 833.35
Formula: C21H26N7O17P3Na4
UV Spectral Analysis: Ratios at pH 10.0
A340/A260 (0.43 ± 0.02)
ε at 260nm(14.4 ± 0.5) x 103
ε at 340nm (6.2 ± 0.2) x 103
Purity: Determined by decrease in absorbance at 340 nm on enzymatic reduction with GR*at pH 10.0 (≧ 95%)
*GR = Glutathion reductase (yeast)(EC 1.6.4.2.)
Sodium Content: 10.0 ± 2.0% 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.
Unstable in acids, but relatively stable at pH 10-11.
Shipping Condition: Refrigerate
