Sildenafil Base (Pharma-Grade Free Base Compound) with CAS 139755-83-2
Unlike the citrate salt, our Sildenafil Free Base is engineered specifically for Laboratory R&D, salt-form screening, and as a critical synthetic building block for advanced molecular synthesis.
Technical Integrity:
Assay: ≥99.0% verified by HPLC.
Impurity Control: Governed by our Unified QC Standard (UQS) to ensure zero synthetic analogs.
Documentation: Batch-specific COA, MSDS, and TDS are provided with every industrial order.
We support Small and Medium-sized Enterprises with Flexible MOQ and Rapid 24-hour Quoting, acting as your strategic extension in the global pharma-ingredient supply chain.
Blue Eye Bio provides Sildenafil Base (Free Base) as a purely defined molecular building block (CAS 139755-83-2) for the global life sciences sector. Unlike the standard citrate salt, our Sildenafil Free Base is engineered for specialized Laboratory R&D where a neutral pH or a specific starting substrate is required for advanced molecular synthesis. Managed under British technical governance, we ensure unrivaled batch consistency from our Asia-based manufacturing hub.

Q: What is the main advantage of Sildenafil Base over Sildenafil Citrate for research?
A: Sildenafil Base is the un-salted form, offering researchers more flexibility in choosing specific acids for salt-form optimization or for use in water-insoluble solvent systems where a neutral charge is required.
Q: Do you offer bulk supply for industrial synthesis? A: Yes. Through our Integrated Manufacturing Hub, Blue Eye Bio can facilitate bulk industrial-scale fulfillment. Every shipment is accompanied by a batch-specific COA and MSDS for regulatory compliance.
Q: Is your Sildenafil Base governed by UK quality standards? A: Absolutely. While production takes place in our Asia facility, all technical oversight and quality audit protocols are managed by our British headquarters, ensuring international pharmaceutical-grade excellence.
