Chemical Structure

Ethylbenzene-d10 CAS 25837-05-2 chemical structure

Description

Owing to deuterium isotope labeling, an aromatic ring system, Ethylbenzene-d10 is typically pale yellow to yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 116.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Ethylbenzene-d10 (CAS 25837-05-2), a certified reference material (molecular formula C8D10, MW 116.23 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
