Product Description

Cisatracurium Besylate (51W89; Nimbex; 51 W89; 51-W89; Cisatracurium besilat), the Besylate salt of Cisatracurium, is a nondepolarizing neuromuscular blocking agent with anesthetic effects. It blocks the transmission of neuromuscular signals, counteracting the effects of acetylcholine. In order to aid in endotracheal intubation and to relax skeletal muscles during surgery or mechanical ventilation, ciprofructurium is used as an adjuvant in anesthesia. One of the ten isomers of the parent molecule, atracurium, is cisatracurium. Moreover, cisatracurium represents approximately 15% of the atracurium mixture.

ln Vitro
Cisatracurium Besylate (51W89) is a skeletal muscle relaxant that belongs to the class of non-depolarizing neuromuscular-blocking medications. It is used as an adjuvant to anesthesia in order to facilitate endotracheal intubation and to provide skeletal muscle relaxation during mechanical ventilation or surgery. It is an agent with an intermediate duration of action that is bisbenzyltetrahydroisoquinolinium. One of the ten isomers of the parent molecule, atracurium, is cisatracurium besylate (51W89). Furthermore, out of the mixture of atracurium, cisatracurium makes up about 15% [1, 2].

Solubility Data
Solubility (In Vitro)
DMSO: 100~249 mg/mL (80.4~200.2 mM)
Water: ~47 mg/mL (~37.8 mM)
Ethanol: ~249 mg/mL (~200.2 mM)
Solubility (In Vivo)
Solubility in Formulation 1: 100 mg/mL (80.42 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 0.8042 mL 4.0210 mL 8.0419 mL
5 mM 0.1608 mL 0.8042 mL 1.6084 mL
10 mM 0.0804 mL 0.4021 mL 0.8042 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. 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
