(Redirected from Diphacinone). Diphenadione is a vitamin K antagonist which has anticoagulant effects and is used as a rodenticide against rats, mice, voles, ground squirrels and other rodents.This chemical compound is an anti-coagulant with longer activity than warfarin and other synthetic indandione anticoagulants.iphenadione is highly toxic for human skin by all means of contact. Consumption of the drug may cause major blood clotting abnormalities and irregular heartbeats. An online pesticide database gives more information about the safety of diphenadione.
Indicators are substances which show whether the substance tested is basic or acidic. 1  pH indicator, a chemical detector for protons in acid-base titrations. 2  Redox indicator, a chemical detector for redox titrations.
In chemistry, we often use symbols to identify elements and molecules. Molecular formula and empirical formula are two such symbolical methods we use to represent molecules and compounds in an easy way. Molecular formula is the formula showing the type of atoms and number of each atom connected in the molecule. Therefore, it gives the correct stoichiometry of each atom. The atoms are depicted by their symbols, which are shown in the periodic table. And the numbers of atoms are written as subscripts.
