Products Description
At room temperature, it usually appears as a yellow oily liquid, but it may also exist in the form of a white to light yellow solid.
A commonly used four-atom N₄ ligand, due to its ability to form stable chelate complexes with various metal ions through two pyridine groups and two amino groups, is widely applied in coordination chemistry, catalysis, and metal ion sensing fields.

FAQ
Q: Can I visit your factory?
A: Sure! Welcome anytime.
Q: How about the payment items?
A: L/C, D/P, T/T.
Q: Can you accept the inspection from a third party?
A: Yes. We have enough experience to cooperate with the inspection project.
Q: How long is the delivery time?
A: Usually, the shipment can be delivered within 10-15 days after the order is confirmed.
Q: Could COA and MSDS documents be provided for each batch?
A: For each batch, we can provide the complete set of COA and MSDS documents.
Q: How stable is the moisture content across different batches?
A: The moisture content shows very little variation across batches and remains stable.
Q: What is the level of heavy metal residues in the product? Will it cause any interference when used as a fluorescent probe?
A: The heavy metal content is less than 10 ppm, which will not interfere with the fluorescence probe detection.
Q: What is the limit for the residual amounts of free ethylenediamine and pyridine? Will it affect the coordination reaction?
A: The residual amounts of free ethylenediamine and pyridine are both ≤ 0.2%, and they will not interfere with the coordination reaction.
