Biological Activity

Description Vanillin, 4-hydroxy-3-methoxybenzaldehyde, is a food additive.
In vitro

Vanillin is a phenolic aldehyde, an organic compound with the molecular formula C8H8O3. Vanilin is a flavorant present in foods, beverages, and tobacco. Vanilin has been evaluated as a potential agent to treat sickle cell anemia. Vanillin has moderate antisickling activity when compared with other aldehydes. Vanillin decreases HbS polymerization by a dual mechanism of action; allosteric modulation to a high-affinity HbS molecule and by stereospecific inhibition of T state HbS polymerization. [1]

In vivo Acute oral LD50 are as follows: rat, 1.58 g/kg, guinea pigs, 1.40 g/kg, and rabbits, 3.0 g/kg. Several oral toxicity studies with rats are reported in which high levels of vanillin are consumed for extensive periods without adverse effect. [1]


Solubility (25°C)

In vitro DMSO 30 mg/mL (197.17 mM)
Ethanol 30 mg/mL (197.17 mM)
Water Insoluble

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
