Magnesium sulfate heptahydrate Specification

 The Magnesium sulfate heptahydrate, with the CAS registry number 10034-99-8, is also known as Bitter salts; Epsom salts; Magnesium sulfate heptahydrate.It belongs to the product categories of Inorganic chemical/inorganic salt. This chemical's molecular formula is MgSO4.7(H2O) and molecular weight is 246.47. What's more,Its systematic name is Magnesium(II),sulfate,heptahydrate. It is a small colorless crystal used as an anticonvulsant, a cathartic, and an electrolyte replenisher in the treatment of pre-eclampsia and eclampsia. It causes direct inhibition of action potentials in myometrial muscle cells. Excitation and contraction are uncoupled, which decreases the frequency and force of contractions. (From AMA Drug Evaluations Annual, 1992, p1083).
