The molecular formula of cetylpyridinium chloride is C 21 H 38 NCl. In its pure form it is a solid at room temperature. It has a melting point of 77 °C when anhydrous or 80–83 °C as a monohydrate. It is soluble in water but insoluble in acetone, acetic acid, or ethanol. It has a pyridine-like odor. It is combustible.
Dentyl contains the powerful antimicrobial agent cetylpyridinium chloride (CPC), which disrupts the membrane – the fatty outer layer – of the bacteria. However, it is atypical in that it also contains isopropyl myristate , an oily, non-aqueous, component that adheres to bacteria making them easier to rinse from the mouth. [ 1 ]
Cetylpyridinium and laurylpyridinium, which can be produced from pyridine with a Zincke reaction, are used as antiseptic in oral and dental care products. [62] Pyridine is easily attacked by alkylating agents to give N-alkylpyridinium salts. One example is cetylpyridinium chloride. Synthesis of paraquat [112]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Coagulation-flocculation process in a water treatment system. In water treatment, coagulation and flocculation involve the addition of compounds that promote the clumping of fine floc into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas ...

The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
