USP/EP-grade Ampicillin Trihydrate (CAS 7177-48-2), 96–102%, supplied wholesale by Zyntex to licensed producers. Aminopenicillin API for oral capsules, suspensions and veterinary products. CoA and SDS with every lot.
Ampicillin trihydrate is a white crystalline powder that is slightly soluble in water. It is the form of ampicillin used in oral products; for injections, producers use the more soluble sodium salt.
Pharmaceutical companies use ampicillin trihydrate in capsules and powders for oral suspension. Veterinary producers use it widely in oral powders, boluses and long-acting injectable suspensions for livestock. In many human oral products, it has been replaced by Amoxicillin 3-hydrate, which is better absorbed.
Related penicillins in our range include Benzylpenicillin Sodium and Flucloxacillin sodium, and the beta-lactamase inhibitor Clavulanate Potassium. As a beta-lactam, it must be handled in dedicated facilities and is supplied only to licensed companies.
