Product Overview
Sodium hexafluorophosphate (NaPF₆) is an inorganic fluorophosphate salt, appearing as free-flowing white crystalline powder. It features good solubility in polar organic solvents and stable electrochemical properties, widely adopted in analytical chemistry, organic synthesis and new energy research.
Sodium hexafluorophosphate is used as an ion pairing agent for the determination of cobalt(II) in water samples. It is used as an important raw material in the preparation of 2-chloro-1,3-bis(dimethylamino)trimethinium hexafluorophosphate.

Application Scenarios
Analytical Chemistry
It works as an ion-pairing reagent for trace metal detection in aqueous matrices. Besides cobalt(II) testing in water samples, it supports qualitative and quantitative analysis of multiple inorganic ions in environmental water, industrial wastewater and saline solution systems.
Organic Synthesis & Catalysis
It acts as a raw material to prepare specialized hexafluorophosphate ionic salts such as 2-chloro-1,3-bis(dimethylamino)trimethinium hexafluorophosphate. It also serves as counter-ion source and phase transfer catalyst for synthesis of benzimidazole and quinoxaline derivatives.
Sodium-ion Battery & Electrochemical Research
As a classic sodium conducting salt, it is widely applied in lab-scale sodium-ion battery electrolyte formulation. It provides sodium ions and forms stable interfacial film, improving ionic conductivity for coin cell and sodium metal battery research.
Material Science Research
Used for preparing polymer composite solid electrolytes and functional ceramic precursors. It helps adjust ionic conductivity of polymer electrolyte membranes for supercapacitor and energy storage material development.
Packaging & Transportation

FAQ
Q1: Is the 98% grade suitable for battery lab research?
A: 98% grade fits most academic and pilot sodium-ion battery research. Higher purity grades (99% / 99.5%) are available upon request for high-precision electrochemical tests.
Q2: Can we accept partial container instead of full FCL?
A: Our standard MOQ is 1 full container. For small trial orders, we can evaluate feasibility separately subject to production schedule.
Q3: What is the shelf life of sodium hexafluorophosphate?
A: 24 months under proper sealed, dry storage. Once the package is opened, consume quickly to avoid moisture absorption.
Q4: Which payment terms can be accepted?
A: T/T is our regular term. We can negotiate payment terms for tender projects.
Q5: Can you mark customized labels for the package?
A: Yes, custom outer packaging labels with customer company information are available.
