Tetraphenylgermane

Updated: 2026-08-30

Overview

Tetraphenylgermane is an organogermanium compound composed of a germanium atom bonded to four phenyl groups. It is a colorless crystalline solid with applications in organic synthesis and material science. The compound is valued for its stability and low reactivity, making it a useful intermediate in various chemical processes. First synthesized in the early 20th century, tetraphenylgermane has since found niche applications in research and industrial settings. Its molecular structure allows it to act as a precursor for more complex organogermanium compounds, which are explored for their potential in electronics and catalysis.

Physical and Chemical Properties

Tetraphenylgermane is a stable, crystalline solid with a melting point of approximately 230-232°C. It is soluble in common organic solvents such as benzene and ether but is insoluble in water due to its non-polar nature. The compound exhibits low reactivity under standard conditions, making it relatively easy to handle in laboratory settings. Its molecular weight is 381.02 g/mol, and it features a tetrahedral geometry around the central germanium atom. The phenyl groups contribute to its hydrophobic character, which influences its solubility and reactivity profile. These properties make it a versatile building block in synthetic chemistry.

Main Applications

Tetraphenylgermane is primarily used in organic synthesis as a precursor for other organogermanium compounds. It serves as a starting material for the preparation of germanium-based catalysts and reagents. In material science, it is explored for its potential in creating germanium-containing polymers and advanced materials. Additionally, the compound is investigated for its electronic properties, particularly in the development of semiconductors and optoelectronic devices. Its stability and predictable reactivity make it a valuable tool in research laboratories focused on organometallic chemistry and nanotechnology.

Safety and Storage

While tetraphenylgermane is relatively stable, proper safety measures should be observed during handling. Avoid inhalation of dust and contact with skin or eyes. Personal protective equipment (PPE), such as gloves and goggles, is recommended when working with this compound. Storage should be in a cool, dry place, away from moisture and oxidizing agents. The compound should be kept in a tightly sealed container to prevent degradation. In case of accidental exposure, rinse affected areas with water and seek medical advice if necessary.

B2B Procurement Guide

When procuring tetraphenylgermane, verify the CAS number (1048-05-1) and purity specifications to ensure product quality. Suppliers typically offer the compound in small quantities, with prices ranging from $200 to $500 per gram, depending on purity and order volume. Bulk orders may qualify for discounts, so it is advisable to negotiate with suppliers for larger quantities. Always request material safety data sheets (MSDS) and certificates of analysis (CoA) to confirm the product meets your requirements. Reliable suppliers often provide technical support for specialized applications.
