Biological Activity

Description Sulfamerazine (RP 2632) is a sulfonamide antibacterial.
In vitro

Sulfamerazine exhibits biexponential decay in water and triexponential decay in cyclodextrins solutions. Sulfamerazine shows remarkably upfield shift in the complexes suggested that the aniline ring deeply encapsulated in the CD cavity. [1]

In vivo Sulfamerazine results in a marked evolution in the shape of the concentration-time curves in function of age, strongly suggesting a defective absorption rate in the first weeks after birth in lambs. [2] Sulfamerazine has a significantly beneficial effect on life span of rats and apparently increases that of male hamsters, and all rats fed sulfamerazine attains higher maximum weights than their controls. [3]


Solubility (25°C)

In vitro DMSO 53 mg/mL (200.52 mM)
Water Insoluble
Ethanol 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 SDS / 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 SDS / 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.
