what are the chemical properties of drugs?
473808
Physicochemical properties underlie all aspects of drug action and are critical for solubility, permeability and successful formulation. Specific physicochemical properties shown to be relevant to oral drugs are size, lipophilicity, ionisation, hydrogen bonding, polarity, aromaticity and shape.

Key Takeaways: Chemical Property A chemical property is a characteristic of a substance that may be observed when it participates in a chemical reaction. Examples of chemical properties include flammability, toxicity, chemical stability, and heat of combustion.

Chemical properties are properties that can be observed or measured when a substances undergoes a chemical change. Physical properties are properties that can be observed without bringing a chemical change.

2.1 CHEMICAL PROPERTIES Each variable in turn has distinct properties. For example, the pulp stock from which a paper is made has specific properties, including crystallinity, fiber bonding, viscosity, and drying, which affect the nature of the final sheet.

Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2).

The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.

Determination of chemical properties results in the change of the identity of the substance. Some properties, such as solubility, melting point, boiling point, and density are independent of the amount of substance being examined. These properties are known as intensive properties and are used to identify a substance.

List properties common to many organic compounds. Many organic compounds have similar properties in terms of melting points, idling points, odor, electrical conductivity, and solubility. ... Measure the melting and boiling point of the materials. Organic material will have lower melting and boiling points.
