Frequently Asked Questions
What should I consider when selecting Ligand families?
When selecting Ligand families, consider the metal precursor, substrate class, and whether the reaction is sensitive to air or moisture. Ligand-to-metal ratio and preformed versus in-situ complex formation often matter as much as the ligand identity.
What does Ligand families cover?
Ligand families is a top-level listing in our catalogue. Use the filters and search on the listing page to narrow by the attributes that matter for your work, or browse the neighbouring categories from the main navigation.
Which data should I check before ordering Ligand families?
Check assay purity for the Ligand families lot, chiral purity where applicable, and appearance, and confirm storage temperature and atmosphere. Oxidised ligand is a common and easily missed cause of failed catalysis. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.
Can I search Ligand families by structure or chirality?
Yes — filter Ligand families by ligand class and chirality, and search by CAS number or SMILES. For preformed metal complexes, bulk quantities, or ligands not listed, contact [email protected].
