Chemicals for the Pharmaceutical Industry
Pharmaceutical manufacturing demands excipients meeting stringent pharmacopeial standards — USP, EP, BP, and IP — with full documentation including CoA, TSE/BSE declarations, and Drug Master File (DMF) support. MITCHEM supplies pharmaceutical-grade magnesium stearate, calcium stearate, zinc stearate, and zinc oxide.

Magnesium Stearate
CAS: 557-04-0 | HS: 29157090
C₃₆H₇₀MgO₄ | 591.24 g/mol
In pharmaceutical tablet manufacturing, Magnesium Stearate is the universal lubricant — added at 0.25–1% to prevent die sticking, reduce punch pickup, and improve tablet ejection in high-speed rotary presses. Our USP/EP grade offers controlled specific surface area and moisture for consistent performance.
Zinc Stearate
CAS: 557-05-1 | HS: 29157090
C₃₆H₇₀O₄Zn | 632.33 g/mol
Pharmaceutical-grade Zinc Stearate functions as both tablet lubricant and excipient in dermatological dusting powders, providing slip and adherence alongside zinc's mild astringent properties.
Zinc Oxide
CAS: 1314-13-2 | HS: 28170010
ZnO | 81.39 g/mol
USP/EP-grade Zinc Oxide is an active pharmaceutical ingredient (API) in topical preparations including sunscreens, barrier creams, calamine lotions, and dermatological ointments.
Calcium Stearate
CAS: 1592-23-0 | HS: 29157090
C₃₆H₇₀CaO₄ | 607.02 g/mol
In pharmaceutical formulations, Calcium Stearate serves as an alternative tablet lubricant and is used in chewable tablets, modified-release formulations, and as a dispersing agent in dry powder inhalers.
Magnesium Carbonate
CAS: 546-93-0 | HS: 28369900
MgCO₃ | 84.31 g/mol
Pharmaceutical-grade Magnesium Carbonate (USP/EP) is used as an antacid API, tablet excipient, and co-lubricant in solid dosage formulations. The light (precipitated) grade is valued as a glidant and desiccant in hygroscopic drug formulations.
