The attached spreadsheet contains the correct CAS numbers for these medications.
If you are sourcing APIs directly
get exactly the CAS numbers specified
get the total weight specified (x2 for 24 weeks treatment)
dose exactly as specified
No Ledipasvir is NOT the same as Ledipasvir acetone, that's why it has a different CAS number.
No Daclatasvir is NOT the same as Daclatasvir 2 hydrochloride (2HCl), that's why it has a different CAS number.
Not Simeprevir is NOT the same as Simeprevir Sodium, that's why it has a different CAS number.
If asked you want Sofosbuvir polymorph Form I if you want the original trial form that is more bioavailable, or Form II (also called 6) if you want what Gilead swapped it out for during commercialisation. It's not a huge deal but go for Form I, it's better.
As there are a few patients out there who have relapsed and who may be looking to other meds for their next round of treatment, do we have the correct API weights for some of the other drugs available from Mesochem?
I'm specifically wondering about Velpatasvir and Simeprevir, but Mesochem currently has eight Hep C meds available, including one more NS5A, one more NS5B and one more NS3/4A.
While we are here please note that CAS numbers are specific and the ones quoted in the spreadsheet are the correct ones. Like Simeprevir, Daclatasvir (CAS 1009119-64-5) is also insoluble which is why Daclatasvir 2HCl (2 hydrochloride salt) (CAS 1009119-65-6) is used.
