Light cream-colored crystalline powder with a slight odor: pH (1% aqueous solution) 6.7. Slight odor. | 【Reactivity Profile】
MERCURY((O-CARBOXYPHENYL)THIO)ETHYL, SODIUM SALT(54-64-8) is incompatible with strong oxidizing agents and strong bases. The oxidation of this compound is greatly accelerated by traces of copper ions. Incompatible with acids, iodine, heavy metal salts and many alkaloids. Can be absorbed by rubber caps. . Stable in air, but not sunlight. May discolor on exposure to light. Dilute aqueous solutions are fairly stable to heat but sensitive to light. Solutions are less stable to heat when acidic than when alkaline. Solutions are most stable to light at pH 5 to 7. Solutions are unstable to heat but not to light in the presence of copper, iron or zinc ions but not in the presence of calcium or magnesium ions. | 【Air & Water Reactions】
Water soluble. | 【Fire Hazard】
Flash point data for this chemical are not available; however, MERCURY((O-CARBOXYPHENYL)THIO)ETHYL, SODIUM SALT is probably combustible. |
