please guide me. how to calculate API salt base to base form (for example: amoxcillin tryhidrate to amoxcillin)
which calculation is right?
1 calculate: (mg/ml)* (100/100-water)(100/assay dryed base)(molecular weight salt/molecular weight base)
2 calculate: (mg/ml)(100/assay dryed base)(molecular weight salt/molecular weight base)
for CoA
water:12,9
assay (dryed base): 100,4
