A-7860 6"-O-Acetylglycitin, >98%
Storage: Store desiccated at or below -20 ºC. Solubility:
Soluble in DMSO, methanol or ethanol. Disposal: A
 | Isoflavone derivative found in soy-based food products. Wang, H. and
Murphy, P.A. "Isoflavone content in commercial soybean foods." J. Agric.
Food Chem. 42: 1666-1673 (1994). |
| STABILITY: Very little information about the stability of this
compound is available at present. In our experience, when stored in the dry
state, frozen and desiccated, this compound has retained its original purity
for several years. We have been informed that aqueous or alcoholic
solutions can undergo substantial decomposition less than a day after being
prepared, particularly if they are held at room temperature. We recommend
that this product be stored in bulk in the dry state, with a desiccant, at
the coldest available temperature. Small working quantities of solutions
should be made up just prior to use. |
| Aqueous solutions of this compound are somwhat unstable, particularly at
room temperature; several percent decomposition can occur in 12-24 hours.
For quantitative work, standard solutions should be made fresh daily. |
| The 1 mg size (+ ca. 2-3%) consists of a film adhering to
the walls of the ampule and may not be easily subdivided by weighing. The
larger sizes contain a weighable powder. |
| The 98% purity figure may include small amounts of acetyl monoesters
other than the 6"-isomer. |
