I agree with you Nobody.

If the analytical response of S-amlodipine present in racemic compound is the same of isolate enantiomer using chiral method, I can determinate the purity.

But, in my case, I do not have a chiral method available in bio-analysis. Then, I keep my doubt...can I use Amlodipine (racemic) instead of S-amlodipine (enantiomeric form) as analitical standard? Both standard are available on the market, but I can not aquire the pure enantiomere in short time.

What are the guaranties of my correct quantification of S-Amlodipine in plasma with a method that do not make any difference between R and S enantiomeres present in analitical reference standard?
