A250/A260 (0.82 ± 0.03)
A280/A260 (0.23 ± 0.02)
A340/A260 (0.43 ± 0.01)
ε at 260 nm: (14.4 ± 0.5) x 103
ε at 340 nm: (6.3 ± 0.2) x 103
Purity: Dertermined by decrease in absorbance at 340 nm on enzymatic oxidation with ADH* at pH 10.0: ≥ 95%
*ADH = Alcohol dehydrogenase (yeast) (EC 1.1.1.1.)
Sodium Content: 6.5 ± 1.5% 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.
