124-20-9


Use Spermidine for free-base polyamine identity checks, salt-form distinction, raw-material comparison, and documentation work tied to CAS 124-20-9.
Spermidine is identified by CAS 124-20-9, molecular formula C7H19N3, and molecular weight 145.25. This page keeps the free-base form separate from salt forms that use different CAS, formula, and molecular-weight values.
The verified identity aligns with Spermidine, 1,5,10-Triazadecane, and N-(3-aminopropyl)butane-1,4-diamine. Salt names, solution formats, and reagent-grade fragments are not used as customer-facing synonyms for this free-base material.
Spermidine may be used in research-material review, analytical planning, and raw-material comparison where a CAS-verified free-base polyamine identity is required. The wording stays within identity, form distinction, and documentation use.
