cGMP Current Good Manufacturing Practices

For pharmaceutical applications, manufacturing of API's (active pharmaceutical ingredients) and intermediates is conducted under current Good Manufacturing Practices (cGMP) in our kilo–lab facility (class 10,000) which has been operational since 1988.


Complete documentation is available for manufacturing under cGMP including validation of stability studies. Active Drug Master Files (DMF's) are maintained in over 20 countries including USA, Europe and Australia (see below).

The Newburyport facility was inspected by the Food and Drug Administration in 2020.
