What is S-Amlodipine Base?
S-Amlodipine Base — also known as Levamlodipine or Leva Amlodipine Base — is the single, enantiopure (S)-form of amlodipine free base, and the pharmacologically active moiety of the racemic drug. It is the common precursor to Prudence Lifecare's enantiopure amlodipine salts: S-Amlodipine Besylate (Levamlodipine Besylate, CAS 150566-71-5) and S-Amlodipine Maleate (Levamlodipine Maleate, CAS 135969-53-8), combining with the respective counter-ion to form each finished salt.

Frequently asked questions
What is S-Amlodipine Base used for?
It is the enantiopure free-base precursor from which S-Amlodipine Besylate and S-Amlodipine Maleate are made.
What is the CAS number of S-Amlodipine Base?
103129-82-4.
What is the molecular formula of S-Amlodipine Base?
C20H25ClN2O5 — the same formula as racemic Amlodipine Base, since it is the isolated (S)-enantiomer.
What is the molecular weight of S-Amlodipine Base?
408.88 g/mol.
Is S-Amlodipine Base the same as Levamlodipine?
Yes — S-Amlodipine, Levamlodipine, Levoamlodipine and l-Amlodipine all refer to the same enantiopure (S)-form.
What is the full chemical name of S-Amlodipine Base?
The chemical (IUPAC) name of S-Amlodipine Base is 3-O-ethyl 5-O-methyl (4S)-2-(2-aminoethoxymethyl)-4-(2-chlorophenyl)-6-methyl-1,4-dihydropyridine-3,5-dicarboxylate. It is also known as Levamlodipine Base; Levamlodipine; S-Amlodipine Base (Leva Amlodipine Base).
What is the S-Amlodipine Base price in India?
The price of S-Amlodipine Base depends on order quantity, grade, documentation requirements and destination. Share your requirement with the Prudence LifeCare sales team to receive a current quotation.
