We’ll be discussing some of the latest developments in chemical about CAS: 125995-03-1, Name is Atorvastatin lactone, molecular formula is C33H33FN2O4. In a Patent,once mentioned of 125995-03-1, Formula: C33H33FN2O4
A process is provided for preparing pharmaceutical grade atorvastatin hemicalcium salt comprising: (a) deesterifying, wherein R is an ester protecting group to (b) extracting R(R*,R*)-3 into an organic solvent or mixture of solvents, (c) adding a base of formula NR1R2R3 wherein R1, R2 and R3 are independently selected from H, substituted or non-substituted C1 to C7 alkyl, C6 to C9 aryl, C8 to C10 aralkyl or aminoalkyl to form atorvastatin base salt, (d) isolating by precipitation of the above atorvastatin base salt and purifying when necessary,
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C33H33FN2O4, you can also check out more blogs about125995-03-1
