Cyclen
Based on 1 Customer Validation
Cyclen is a macrocyclic tetraamine chelating agent. Cyclen is the aza analogue of crown ether, used as a precursor for MRI contrast agents, and is an intermediate for the preparation of effective macrocyclic chelates. Cyclen is employed as a structural regulator through interfacial polymerization of polyethleneimine (PEI) and trimesoyl chloride (TMC) to develop polyamide NF membrane with efficient Li+/Mg2+ separation performance. Cyclen has specific cavity structure and exhibits selective coordination properties for Li+ ions[1][2].

Cyclen binds dehydrated Li+ with an adsorption energy of -75.0 kJ/mol, forming a stable complex due to a well-matched molecular cavity size[2].
Cyclen in PEI/Cyclen-TMC composite membrane reduces the Mg2+/Li+ mass ratio of simulated salt lake brine from 40 to 0.3 over three nanofiltration stages, achieving a 45.5% Li+ recovery rate and producing Li2CO3 with 93% purity after precipitation and filtration[2].

Lösungsmittel & Löslichkeit
H2O : 50 mg/mL (290.23 mM; Need ultrasonic)
DMSO : 1.85 mg/mL (10.74 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
