Is L-ascorbic acid, Product A5960, the same as vitamin C?
Yes, L-ascorbic acid is a synonym for vitamin C.
What is the solution stability of L-ascorbic acid, Product A5960?
Aqueous solutions are stable only in the absence of oxygen. Aqueous solutions are most stable at pH 5-6, very unstable at alkaline pH. (Data for Biochemical Research, 3rd ed., Dawson, R. M. C., et al., Oxford University Press (New York, NY: 1986), p. 116) Degradation is markedly increased in the presence of transition metal ions, especially Cu(II) and Fe(III). The first stage of oxidation of L-ascorbic acid to dehydroascorbic acid is reversible and the biological activity is retained. Further oxidation to 2,3-diketogulonic acid is not reversible and the activity is lost. (Omura, H., and Yamafuji, K., in Methodicum Chimicum, 11(2), Korte, F., and Goto, M., eds., Academic Press (New York, NY: 1977), p. 115).
What is the pKa of L-ascorbic acid, Product A5960?
The pKa values for L-ascorbic acid (from the chemicals encyclopedia published by the Royal Society of Chemistry) are 4.17 and 11.57.
What is the extinction coefficient of L-ascorbic acid, Product A5960?
According to the Data for Biochemical Research, 3rd ed., Dawson, R. M. C., et al., Oxford University Press (New York, NY 1986), p. 116, the L-ascorbic acid extinction coefficient: EmM = 7.0 (265 nm, water), 7.5 (245 nm, acid).
