Isopropyl benzoate is used as a solvent and as a fragrance ingredient in cosmetics and personal care products. It is also used as a flavoring agent and as an intermediate in organic synthesis. The compound is not used as a pharmaceutical agent.
Biological Activity I Assay Protocols (From Reference)
Targets
Isopropyl benzoate does not have a pharmacological target. It is an industrial chemical and fragrance ingredient. Its mechanism of action is not relevant to biological systems, as it is not intended for therapeutic use. It may interact with biological systems as a mild irritant, but this is not a pharmacological effect.
ln Vitro
Isopropyl benzoate is not used in pharmacological activity assays. Its properties are evaluated in the context of its use as a solvent, fragrance, and flavoring agent. Its chemical and physical properties, such as odor, solubility, and stability, are characterized for these applications. It is not used in standard pharmacological in vitro assays.
ln Vivo
Isopropyl benzoate is not used as a drug and does not have in vivo pharmacological activity. Its effects are observed in industrial applications where it is used as a solvent or fragrance ingredient. It is not administered to animals or humans for therapeutic purposes.
Enzyme Assay
As an industrial chemical and fragrance ingredient, isopropyl benzoate does not have a typical enzyme/receptor binding assay. Its properties are assessed based on its chemical and physical characteristics, such as purity, odor, and stability. It is not used in standard pharmacological binding assays.
Cell Assay
Isopropyl benzoate is not typically used in cell-based assays. Its applications are primarily in the fragrance, flavoring, and chemical industries. The compound's effects on cells are not a primary focus of study, as it is not intended for biological or therapeutic use. Its safety in biological systems may be assessed for regulatory purposes.
Animal Protocol
Isopropyl benzoate is not used in animal experiments for pharmacological purposes. Its effects are studied in the context of its use as a fragrance and flavoring agent. Animal studies may be conducted for toxicological evaluation to assess its safety for use in consumer products, but these are not typical pharmacological studies.
ADME/Pharmacokinetics
Isopropyl benzoate has a molecular weight of 164.20 and a molecular formula of C10H12O2. It is a colorless liquid with a boiling point of approximately 218°C. It is practically insoluble in water but soluble in organic solvents. Its physical properties are characterized for its use as a solvent and fragrance ingredient.
Toxicity/Toxicokinetics

Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 5.4289 mL 27.1444 mL 54.2888 mL
5 mM 1.0858 mL 5.4289 mL 10.8578 mL
10 mM 0.5429 mL 2.7144 mL 5.4289 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
