Chemical Structure

Ethylbenzene CAS 100-41-4 chemical structure

Description

CATO supplies Ethylbenzene (CAS 100-41-4), a certified reference material (molecular formula C8H10, MW 106.17 g/mol) for analytical method development and quality control.

The molecular framework of Ethylbenzene (C8H10) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
