Description

Phosphazene Base P1-T-Oct is a powerful, non-ionic, sterically hindered organic superbase belonging to the phosphazene family. Its exceptional basicity and low nucleophilicity make it an invaluable catalyst and reagent for demanding deprotonation and polymerization reactions where traditional metal alkoxides or alkali metal amides are unsuitable. This compound is essential for researchers and process chemists in advanced pharmaceutical synthesis, specialty polymer production, and materials science. The product is commercially supplied under the identifier CAS No. 161118-69-0.

Application

• Polymerization Catalyst: Highly effective initiator for the anionic ring-opening polymerization (ROP) of lactones, lactides, and other cyclic monomers to produce biodegradable polyesters like PLA and PCL.
• Pharmaceutical Intermediate Synthesis: Used as a strong, non-metallic base for the generation of reactive enolates and carbanions in multi-step API synthesis, minimizing metal contamination.
• Organic Synthesis Reagent: Facilitates challenging deprotonations, isomerizations, and condensation reactions under mild conditions, often superior to DBU or MTBD.
• Materials Science Research: Employed in the development of advanced polymeric materials, dendrimers, and supramolecular structures requiring precise base control.
• Lithium-Ion Battery Electrolyte Additive: Investigated for use as a stabilizer or proton scavenger in high-performance electrolyte formulations.

Quality Control

Every batch of Phosphazene Base P1-T-Oct is manufactured and tested under strict quality management protocols to ensure consistent high purity and performance. Our standard grade typically meets a purity specification of ≥98% (by NMR or HPLC). Comprehensive Certificates of Analysis (COA) are provided with each shipment, detailing key parameters such as assay, identity, and moisture content. We can support development and production needs requiring compliance with cGMP or other stringent regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and tendency to be easily oxidized (store under inert atmosphere), this material must be stored under a dry, inert gas atmosphere (argon or nitrogen) in a cool, dry place at 2-8°C. For long-term storage, keep containers sealed and desiccated. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
