Description

Tris(Tetrabutylammonium) Hydrogen Pyrophosphate CAS NO 76947-02-9 is a high-purity, organoammonium salt of pyrophosphoric acid, serving as a versatile and highly soluble source of pyrophosphate ions in non-aqueous and specialized reaction media. Its primary value lies in its ability to act as a phase-transfer catalyst and a mild, non-nucleophilic base in organic synthesis, particularly for sensitive reactions where traditional inorganic bases are unsuitable. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise control over phosphorylation and condensation reactions under anhydrous conditions.

Application

• Phase-Transfer Catalyst (PTC): Facilitates the transfer of pyrophosphate anions into organic phases for nucleophilic substitution and phosphorylation reactions.
• Pharmaceutical Intermediate Synthesis: Used in the preparation of nucleotide analogs, prodrugs, and other bioactive phosphate esters.
• Polymerization Catalyst: Acts as a catalyst or initiator in the synthesis of specific polyphosphates and specialty polymers.
• Agrochemical Manufacturing: Employed in the synthesis of phosphate-based herbicides, plant growth regulators, and fungicides.
• Electrolyte Additive: Investigated for use in advanced battery systems and electrochemical applications.
• Laboratory Reagent: Serves as a specialized reagent for biochemical research and analytical chemistry methods.

Quality Control

Our Tris(Tetrabutylammonium) Hydrogen Pyrophosphate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for water content, to ensure it meets stringent specifications for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong bases and incompatible materials.
