Product Description
Pimobendan is an organic benzimidazole-pyridazinone compound used as an active ingredient in regulated veterinary prescription products. It is generally supplied as a crystalline powder and is characterized pharmacologically as a calcium sensitizer and phosphodiesterase III inhibitor.
Pimobendan API is intended for qualified veterinary pharmaceutical manufacturers, analytical laboratories and authorized research organizations. It is not a finished veterinary medicine and must not be administered directly to animals.

Product grade, pharmacopoeial status, manufacturing site and regulatory documentation must be confirmed in AOZUN’s formal quotation.
Pimobendan is used in prescription veterinary medicines approved in certain markets for specific canine cardiac conditions. Approved indications, dosage forms, strengths and labeling vary between countries.
Bulk pimobendan must not be promoted or supplied as a finished medicine. Commercial veterinary formulation requires:
An appropriately licensed manufacturer
Compliance with the destination market’s veterinary-drug regulations
A qualified API source
Approved formulation and manufacturing procedures
Required stability, safety and efficacy data
Regulatory authorization before marketing
This product page provides B2B raw-material information and does not constitute medical or veterinary advice.
These product types are not interchangeable.
Veterinary API is manufactured and controlled for use in regulated veterinary pharmaceutical production. Qualification may include GMP status, validated analytical methods, impurity control, stability data and regulatory support.
Research-grade pimobendan is intended for laboratory investigation or method development. A research product should not be used to manufacture commercial veterinary medicines unless it has been separately qualified as an API.
An official reference standard is used for analytical testing, identification or assay calibration. It is not commercial bulk API and normally comes in a small defined quantity.
The required product type should be stated clearly in every inquiry.
Quality attribute | Why It Matters |
Identity | Confirms the correct chemical substance |
Assay | Measures pimobendan content |
Related substances | Controls process impurities and degradation products |
Specified impurities | Supports pharmacopoeial and regulatory compliance |
Residual solvents | Verifies control of manufacturing solvents |
Water content | Affects stability and calculation on a dry basis |
Elemental impurities | Supports risk assessment and regulatory compliance |
Residue on ignition | Indicates nonvolatile inorganic residue |
Polymorphic form | May affect processing and dissolution behavior |
Particle-size distribution | Influences blending and formulation performance |
Stereochemical identity | Confirms the required racemic or specified form |
Microbial quality | May be required according to process and dosage form |
Stability or retest period | Supports storage and inventory control |
An assay result alone is not sufficient to qualify pimobendan for regulated veterinary formulation.
Pimobendan has limited aqueous solubility. Consequently, crystal form, particle size, surface area and formulation conditions can influence powder handling and dissolution behavior.
Buyers should confirm:
Polymorphic or crystalline form
Particle-size test method
Requested D10, D50 and D90 limits where applicable
Milling or micronization status
Bulk and tapped density
Hygroscopicity and moisture controls
Compatibility with the intended formulation process
Any change in manufacturing process, crystallization or milling should be evaluated through the customer’s change-control and formulation-qualification procedures.
Depending on the grade and regulatory market, buyers may request:
Approved product specification
Lot-specific Certificate of Analysis
Current Safety Data Sheet
GMP certificate or manufacturing authorization
Manufacturing-site information
Analytical method summary
Impurity and residual-solvent statements
Elemental-impurity risk assessment
Stability data and proposed retest period
TSE/BSE, allergen or GMO statements where relevant
Regulatory file information such as DMF or ASMF, where available
Change-control and traceability information
Document availability must be verified before claiming GMP, USP, EP, DMF, ASMF or other regulatory status.
Pimobendan is covered by official pharmacopoeial resources in some markets. However, the existence of a monograph does not automatically mean that every commercial batch is pharmacopoeial grade.
The purchase specification should identify:
Applicable pharmacopoeia or in-house standard
Required assay range
Individual and total impurity limits
Residual-solvent requirements
Water-content method
Particle-size requirements
Packaging and storage conditions
Required regulatory documents
Final acceptance should be based on an approved specification and lot-specific test results.
Packaging depends on grade, quantity and manufacturer. Small quantities are normally packed in sealed inner containers with suitable secondary protection.
Store pimobendan:
In the original tightly sealed container
Under the temperature stated in the approved specification
Protected from light, heat, air and moisture
In a controlled pharmaceutical or laboratory storage area
Separately from incompatible materials
With access limited to trained personnel
Storage conditions differ between API, research reagent and reference-standard products. Always follow the supplied label, COA and SDS.
AOZUN can support qualified B2B buyers with:
API and research-grade requirement clarification
Manufacturer and specification matching
COA, SDS and available regulatory-document review
Sample coordination for analytical evaluation
Packaging and international-shipping coordination
Lot and manufacturing-site traceability
Communication of customer-specific impurity or particle-size requirements
API status, GMP claims, pharmacopoeial compliance and regulatory-file availability must be confirmed for the specific manufacturer and production site.
Pimobendan is an organic compound containing carbon, hydrogen, nitrogen and oxygen. It belongs to the benzimidazole-pyridazinone chemical class.
Commercial pimobendan is normally classified as a high-value fine chemical and veterinary active pharmaceutical ingredient. It is not normally categorized as a synthesis intermediate.
No. Research-grade material must not be assumed to meet veterinary API requirements. Commercial formulation requires appropriately qualified API and regulatory documentation.
No. API qualification also requires control of identity, impurities, residual solvents, water, elemental impurities, solid form, particle size and stability.
