Sodium Glucoheptonate (CAS# 31138-65-5) is a water-soluble organic compound derived from glucose with the molecular formula C7H13NaO8 and a molecular weight of 248.16. Also known as glucoheptonic acid sodium salt or sodium glucoheptonate dihydrate, it is a chelating agent that forms stable complexes with metal ions. The compound takes the form of a white powder and is freely soluble in water. Sodium Glucoheptonate is used for cleaning metal, mercerizing, paint stripping, and aluminum etching. It is also used to mercerize cotton, linen, and other plant-based fibers.
Biological Activity I Assay Protocols (From Reference)
Targets
Sodium Glucoheptonate targets metal ions as a chelating agent. The compound's multiple hydroxyl groups and carboxylate group provide coordination sites for binding metal ions such as calcium, magnesium, iron, and other transition metals. This chelating property makes it useful for industrial applications including metal cleaning and fiber processing. Its targets are chemical rather than biological, as it is primarily used in industrial applications rather than as a therapeutic agent.
ln Vitro
In vitro studies of Sodium Glucoheptonate have focused on its role as a chelating agent and its industrial applications. The compound's ability to form stable complexes with metal ions has been characterized. Its solubility in water (freely soluble) supports its use in various applications. These in vitro studies provide foundational data for understanding the compound's utility in industrial and research applications.
ln Vivo
Tc-99m glucoheptonate shows a fairly constant blood level and quick blood clearance[2].
In vivo studies of Sodium Glucoheptonate are limited as the compound is primarily used in industrial applications rather than as a therapeutic agent. The compound is not intended for administration to living organisms for pharmacological evaluation. Its applications are limited to industrial uses including cleaning metal, mercerizing, and paint stripping. The compound is not approved for human therapeutic use.
Enzyme Assay
In vitro chemical assays for Sodium Glucoheptonate involve testing its chelating properties. The compound's ability to bind metal ions is assessed using spectroscopic or analytical methods. Its purity (≥95%) and identity are confirmed using analytical chemistry methods such as high-performance liquid chromatography and mass spectrometry. All assays are performed with appropriate controls and standardized protocols to ensure reproducibility of results.
Cell Assay
In vitro cell-based assays are not applicable for Sodium Glucoheptonate as the compound is primarily used in industrial applications rather than as a biological agent. The compound is not intended for cell-based studies as a direct pharmacological agent. Its applications are limited to industrial uses including metal cleaning and fiber processing. Cell-based assays may be used for toxicology assessment, but the compound is not studied as a therapeutic agent.

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)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
