Vardenafil CAS 224785-90-4

FAQ - Technical & Supply Chain

• Q:

  Does CAS 224785-90-4 identify Vardenafil free base or Vardenafil hydrochloride trihydrate?

  A: Vardenafil, CAS 224785-90-4, is the free-base form of Vardenafil. It is not Vardenafil hydrochloride trihydrate, which has a different CAS number and formula. State the exact free-base identity, CAS and form in the specification.
• Q:

  Which Vardenafil form should be confirmed before requesting a quotation?

  A: Confirm free-base identity, salt or hydration state, specification, intended use, applicable regulatory requirements and document needs. The quotation should identify the precise chemical form and not rely on the name Vardenafil alone.
• Q:

  Which specifications should be agreed for Vardenafil?

  A: Confirm assay and method, physical form, water or loss on drying, related substances, residual solvents, particle size where relevant and any required compendial or reference-standard basis. The product specification should correspond to the exact free-base form and lot.
• Q:

  What regulatory requirements should be reviewed before procurement?

  A: For regulated or pharmaceutical use, the buyer must confirm applicable regulatory requirements, documentation and local compliance before procurement. The product page does not establish a therapeutic, dosage or finished-product claim.
• Q:

  What appearance, melting range and solubility should be expected for Vardenafil free base?

  A: Vardenafil free base (CAS 224785-90-4; C23H32N6O4S) is a solid, but its melting behaviour depends on crystal form and test method. Do not use a hydrochloride-hydrate melting range as the free-base specification. For procurement, request the offered lot's appearance, melting or DSC method, water content and solubility data, and verify the chemical form against the COA/TDS/SDS.
