Biological Activity

Description Otilonium bromide is an antimuscarinic.
mAChR [1]
In vitro

Otilonium bromide is a quaternary ammonium compound whose spasmolytic action, selective on the distal gastrointestinal tract, is mainly due to its direct myolytic properties. [1] This drug modifies Ca2+ fluxes from extracellular and intracellular pools in the intestinal smooth muscle and is poorly absorbed, thus it exerts its action locally, without any considerable systemic effect. [2]


Solubility (25°C)

In vitro DMSO 113 mg/mL (200.5 mM)
Water 113 mg/mL (200.5 mM)
Ethanol 113 mg/mL (200.5 mM)

* 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.
