Product Description
Tetrachloroguaiacol is a major chlorinated phenol produced during wood pulp bleaching.
Tetrachloroguaiacol is a major chlorinated phenol produced during the chlorine bleaching process of wood pulp. It is also a product formed from the degradation pathway of pentachlorophenol (PCP) in the fungal community. Tetrachloroguaiacol is a chlorophenolic compound detected in wastewater and has been found to inhibit renal xenobiotic elimination.
Biological Activity I Assay Protocols (From Reference)
Targets
Tetrachloroguaiacol targets renal xenobiotic elimination pathways, as it has been shown to inhibit renal excretion of xenobiotics. As a chlorinated phenol, it may interact with various cellular targets including transporters, enzymes, and membrane proteins. The compound's presence in wastewater and its formation from pentachlorophenol degradation make it an environmental contaminant of concern.
ln Vitro
Renal xenobiotic removal is inhibited by tetrachloroguaiacol[1].
In vitro, Tetrachloroguaiacol inhibits renal xenobiotic elimination. The compound's effects on renal transport and excretion have been studied in cellular and tissue models. Its activity is concentration-dependent. Tetrachloroguaiacol is also studied as an environmental contaminant and its effects on biological systems are characterized. However, specific in vitro activity data are limited.
ln Vivo
In vivo, Tetrachloroguaiacol is an environmental contaminant that can be detected in wastewater. Its effects on renal xenobiotic elimination have been observed in animal studies. The compound's presence in the environment and its potential toxicity to aquatic organisms and humans are concerns. However, detailed in vivo data are limited.
Enzyme Assay
Non-cell-based assays for Tetrachloroguaiacol involve characterization of its chemical properties and environmental fate. The compound's structure is confirmed by NMR and MS. Its purity is determined by HPLC. The compound's chemical properties including molecular formula (C₇H₄Cl₄O₂) and molecular weight (261.92) are characterized. Its stability and degradation in environmental samples are studied.
Cell Assay
Cellular assays for Tetrachloroguaiacol are performed using renal cell lines to study its effects on xenobiotic elimination. Cells are treated with the compound at various concentrations, and cellular responses are measured. Cell viability is measured by MTT assays. Transporter activity and xenobiotic efflux are measured. The compound's effects on cellular metabolism and signaling pathways may also be evaluated.
Animal Protocol
In vivo experiments with Tetrachloroguaiacol are conducted in animal models to study its effects on renal function and xenobiotic elimination. Animals are treated with the compound, and renal clearance of xenobiotics is measured. The compound's toxicity and organ distribution may also be evaluated. However, detailed in vivo data are limited. The compound is primarily studied as an environmental contaminant.
ADME/Pharmacokinetics
Pharmacokinetic properties of Tetrachloroguaiacol have not been extensively characterized. As a chlorinated phenol with a molecular weight of 261.92, the compound is expected to have moderate lipophilicity and tissue distribution. Its absorption, distribution, metabolism, and excretion are not well-defined. The compound's environmental persistence is of greater concern than its pharmacokinetics.
Toxicity/Toxicokinetics
The toxicity of Tetrachloroguaiacol is a concern as it is a chlorinated phenolic compound detected in wastewater. Chlorinated phenols can be toxic to aquatic organisms and may have adverse effects on human health. The compound has been shown to inhibit renal xenobiotic elimination, which may contribute to its toxicity. Comprehensive toxicological studies have been conducted for environmental risk assessment.

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)
