Biological Activity

Description Sulfathiazole is an organosulfur compound that has been used as a short-acting sulfa drug.
In vitro

Sulfathiazole (20 μg/L) starts to be degraded between day 31 and day 38 in one of the two batch reactors containing different wastewater matrices. Sulfathiazole is degraded at a substantially faster rate than sulfamethoxazole or sulfamethazine in the nitrification process (S3). [1] Recovery from spiked manure slurry samples is 64% for Sulfathiazole at pH 9. Sulfathiazole has acidity constant of pKa of 7.1and retention times (tR) of 7.8. S/N values for Sulfathiazole are above 100 at the 1 mg/kg level. [2] Sulfathiazole sorption to inorganic sorbents exhibits pronounced pH dependence consistent with sorbate speciation and sorbent charge properties. Sulfathiazole cations are most important for sorption to clay minerals, followed by neutral species. [3] Sulfathiazole posseses at least five crystalline or polymorphic forms: I, II, III, IV and V. Although both amido and imido forms are possible for the sulfathiazole molecule, the Sulfathiazole exists in the solid state in the imido form. [4] Sulfathiazole (94.9 mg/L) causes a significant increase in reactive oxygen species (ROS) generation and lipid peroxidation in the presence of ultraviolet B (UV-B) light. Exposure to Sulfathiazole and UV-B light causes apparent up-regulation of alpha-esterase, hemoglobin, and vitellogenin mRNA and significantly affect the survival of daphnids. [5]

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.
