Desacetylcinobufagin
Desacetylcinobufagin is a bufadienolide steroidal glycoside with the molecular formula C24H32O5 and CAS number 4026-95-3, supplied as a white crystalline powder. The product has a purity of at least 95% by HPLC, a melting point of 129 - 130°C, and is stored under refrigerated conditions between 2 - 8°C to maintain stability. It is derived from toad venom secretions and is used exclusively as a pharmaceutical intermediate in research settings.
This compound belongs to the bufadienolide class, known for their cardiotonic and cytotoxic properties. Typical industry standards for such intermediates require a moisture content below 1.5% and foreign matter under 0.5%, though these are not guaranteed by the supplier. The predicted boiling point is 601.9°C at 760 torr, and the density is approximately 1.31 g/cm³ at 20°C. Stability under light exposure is critical; storage in amber glass or opaque containers is standard practice.
Buyers include pharmaceutical R&D labs, API manufacturers, and academic institutions focused on cardiovascular and oncology drug discovery. The compound is typically shipped in sealed, moisture-proof containers under inert atmosphere, with quantities ranging from 1 gram to 5 kilograms. Export documentation must include a Certificate of Analysis, safety data sheet, and classification under UN 3249 for dangerous goods. Lead time and MOQ must be confirmed directly with the supplier.

Sourcing Desacetylcinobufagin from Sichuan Weiekqi Biological Technology Co., Ltd. - China Import Guide
Before placing an order, verify the Certificate of Analysis includes HPLC chromatograms with peak areas, moisture content via Karl Fischer, and heavy metal limits if intended for human use. Confirm the CAS number matches 4026-95-3 and the molecular weight aligns with C24H32O5. Request batch-specific data, not generic templates. Do not accept certificates without a lab stamp or signature.
Logistics must be coordinated under DDP or FOB terms, with the supplier providing export documentation for UN 3249 hazardous goods. Lead time is typically 15 - 25 days from order confirmation, but no guarantee is provided. Payment terms are usually 50% advance, 50% against shipping documents. Confirm if the supplier uses a licensed dangerous goods forwarder and whether temperature-controlled shipping is available.
Quality inspection should include visual checks for color consistency, moisture detection, and HPLC validation against a reference standard. Request a sample of the batch prior to full shipment. Documentation must include a declaration of origin, SDS in English, and a statement confirming no animal testing was performed unless required by regulation. Retain samples for 12 months for audit purposes.
