Brief Introduction
Spironolactone is a synthetic 17-spironolactone corticosteroid with potassium-sparing diuretic, antihypertensive, and antiandrogen activities.Spironolactone competitively inhibits adrenocortical hormone aldosterone activity in the distal renal tubules, myocardium, and vasculature. This agent may inhibit the pathophysiologic effects of aldosterone produced in excess by various types of malignant and benign tumors.

1,1'-Carbonyldiimidazole; Di(1H-Imidazol-1-Yl)Methanone; Carbonyldiimidazole
Brief Introduction
N. N ′ - carbonyldiimidazole (CDI) is a derivative of imidazole, which has a closed large p-bond in the structure of imidazole and a pair of lone pair electrons in the non bonded SP2 orbital of one nitrogen atom. All these determine that CDI has strong chemical reaction activity, and can react with ammonia, alcohol, acid and other functional groups to synthesize many compounds which are difficult to obtain by general chemical methods. It is widely used as an enzyme and protein binder, as an intermediate of antibiotics, especially as a bonding agent for the synthesis of peptide compounds.

Brief Introduction
1,3-Dichlorobenzene is an organic compound with the formula C6H4Cl2. It is the least common of the three isomers of dichlorobenzene, it is a colorless liquid that is insoluble in water. It is produced as a minor byproduct of the chlorination of benzene, but can also be prepared in a directed manner by the Sandmeyer reaction of 3-chloroaniline. It also arises from the isomerization of the other dichlorobenzenes at high temperature.Used in organic synthesis. The Friedel-Crafts reaction between m-dichlorobenzene and chloroacetyl chloride yields 2,4,ω-trichloroacetophenone, which is used as an intermediate for the broad-spectrum antifungal drug miconazole. The chlorination reaction is carried out in the presence of ferric chloride or aluminum mercury, and 1,2,4-trichlorobenzene is mainly produced. In the presence of a catalyst, it is hydrolyzed at 550-850°C to produce m-chlorophenol and resorcinol. Using copper oxide as a catalyst, it reacts with concentrated ammonia at 150-200°C under pressure to generate m-phenylenediamine. 2. Used in dye manufacturing, organic synthesis intermediates and solvents.
