Description

Di-tert-Butyl Selenide, 99.99+%, Electronic Grade is a high-purity organoselenium compound of significant importance in advanced materials synthesis. Its primary value lies in its role as a volatile selenium precursor for the deposition of high-quality selenide thin films. This product is essential for manufacturers and R&D facilities in the semiconductor, photovoltaics, and optoelectronics industries, where ultra-high purity is non-negotiable for device performance and yield.

Application

• Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD): As a key selenium source for depositing metal selenide films (e.g., Cu(In,Ga)Se₂ - CIGS) in thin-film solar cells.
• Semiconductor Manufacturing: Precursor for the synthesis of II-VI semiconductor nanocrystals and quantum dots with precise optical properties.
• Optoelectronic Devices: Used in the fabrication of photodetectors, light-emitting diodes (LEDs), and other devices requiring high-purity selenide layers.
• Research & Development: Serves as a fundamental reagent in organometallic chemistry and materials science for developing new selenium-containing compounds.
• Catalysis: Potential ligand or precursor in catalytic systems for organic synthesis.

Quality Control

Our Electronic Grade Di-tert-Butyl Selenide is produced and tested under stringent conditions to meet the exacting requirements of the semiconductor and photovoltaics industries. Quality is assured through rigorous analytical methods including GC, ICP-MS, and NMR to verify the 99.99+% purity and control critical metallic impurities at sub-ppm levels. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry, well-ventilated area. Due to its highly volatile and easily oxidized nature, minimize exposure to air and handle in a controlled environment.
