Launch of High-Purity Ethyl Viologen Dibromide (CAS 53721-12-3) Empowering Global R&D in Electrochromic and Energy Storage Materials

May 29, 2026, Shanghai — Shanghai Massive Chemical Technology Co., Ltd., a leading supplier of fine chemicals and specialty materials, today announced the official launch of high-purity Ethyl Viologen Dibromide (CAS 53721-12-3) to meet the rapidly growing demand from global research institutions, electronic material enterprises and new energy manufacturers in fields including electrochromic devices, redox flow batteries, sensing and analysis, and more.

Core Product Advantages

Ethyl Viologen Dibromide (1,1'-Diethyl-4,4'-bipyridinium Dibromide), a classic viologen derivative, has become a key reagent in functional materials owing to its unique reversible redox properties and excellent electrochromic performance. The product launched this time features the following advantages:

Ultra-high purity: Produced with an efficient purification process, with a purity of ≥98.0% (HPLC), and up to 99% for selected batches. Impurity residues are strictly controlled to ensure stability in R&D and mass production.

Stable quality: White to pale yellow crystalline powder with uniform appearance; melting point approximately 278°C, with physical and chemical parameters consistent with international standards.

Global supply: Available in research-scale packages (1g, 5g, 25g) to industrial-grade kilogram quantities, supporting fast global delivery.

Complete certification: Full set of technical documents including MSDS, COA and HPLC chromatogram are provided with each shipment, complying with international standards such as REACH and ISO.

Core Application Fields

Electrochromic Devices (Smart Windows / Displays)

As a high-performance electrochromic active material, it is colorless and transparent in the oxidized state and rapidly turns deep blue in the reduced state, with outstanding cycling stability. It is widely used in smart glass, anti-glare rearview mirrors, flexible displays and other applications.

New Energy Storage (Redox Flow Batteries / Organic Electrodes)

With excellent electron transfer capability, it is used as a redox mediator to improve energy efficiency and cycle life in aqueous redox flow batteries and organic ion batteries.

Analytical Detection and Sensing

Commonly used as an internal standard for the quantitative analysis of paraquat, suitable for HPLC, LC-MS and other methods for herbicide detection in biological and environmental samples.

Photocatalysis and Optoelectronic Materials

As an electron transfer mediator, it is applied to interface modification in dye-sensitized solar cells and perovskite devices to enhance charge transport efficiency.
