Chemical Structure

Tetraphenylgermane CAS 1048-05-1 chemical structure

Description

The occurrence of Tetraphenylgermane is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tetraphenylgermane (CAS 1048-05-1), a certified reference material (molecular formula C24H20Ge, MW 381.06 g/mol) for analytical method development and quality control.

Owing to a polycyclic aromatic system, Tetraphenylgermane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
