This list of pharmaceutical compound number prefixes provides codes used by individual pharmaceutical companies when naming their pharmaceutical drug candidates. . Pharmaceutical companies generally produce large numbers of compounds in the research phase for which it is impractical to use often long and cumbersome systematic chemical names, and for which the effort to generate nonproprietary ...
[Mg(H 2 O) 6] 2+ → [Mg(H 2 O) 5 (OH)] + + H 3 O + (decomposes in water) MgCl 2 ·nH 2 O → Mg(OH)Cl + HCl + (n-1)H 2 O (decomposes when heated) Magnesium chloride is an ionic compound, which can be electrolysed in a molten state to form magnesium and chlorine gas. The properties of magnesium bromide and magnesium iodide are similar.
IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
Because the S 2− anion has a subscript of 2 in the formula (giving a 4− charge), the compound must be balanced with a 4+ charge on the Pb cation (lead can form cations with a 4+ or a 2+ charge). Thus, the compound is made of one Pb 4+ cation to every two S 2− anions, the compound is balanced, and its name is written as lead(IV) sulfide.
