Maropitant API

High-Purity Intermediate for Injectable & Oral Veterinary Products

Maropitant is supplied as a high-purity crystalline API intended for veterinary injectable and oral antiemetic formulations. It is designed for formulation scientists, R&D teams, and procurement professionals who require analytical consistency, controlled handling characteristics, and dependable supply.

This material is not a finished veterinary drug product and is supplied strictly as an API for formulation, development, and manufacturing.

Quality & Performance in Formulation

Lot-to-Lot Consistency

Incoming batches include HPLC retention times and assay values, allowing QC teams to compare results against internal reference standards prior to formulation trials.

Moisture Control & Stability

As a crystalline small-molecule API, Maropitant is sensitive to moisture exposure, which may affect:

▸ Flow properties

▸ Dissolution behavior

▸ Downstream processing

To mitigate these risks, the product is packaged using moisture-barrier materials with desiccants.

Solvent Compatibility

Compatible with organic solvent systems commonly used in veterinary injectable and oral dosage forms, subject to internal formulation protocols.

Handling, Storage & Logistics

▸ Shipping: Ambient or refrigerated

▸ Short-term storage: 2–8 °C

▸ Long-term storage: −20 °C

▸ Moisture protection: Keep containers tightly sealed

Allow unopened containers to reach room temperature before opening to prevent condensation and preserve material integrity.

Procurement & Supply Process

Evaluation orders: Small-quantity samples for QC and formulation testing
Documentation review: COA matching and optional extended data
Scale-up supply: Structured bulk agreements with defined volumes and lead times
