Chemical Structure

Ethyl-alpha-13C-benzene CAS 287399-32-0 chemical structure

Description

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.

Ethyl-alpha-13C-benzene (CAS 287399-32-0), molecular formula C7[13C]H10 and molecular weight 107.16 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7[13C]H10, Ethyl-alpha-13C-benzene contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 107.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
