Chemical Structure

2-(Tert-butyl)quinoxaline CAS 18503-48-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 186.25 g/mol gives 2-(Tert-butyl)quinoxaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(Tert-butyl)quinoxaline (CAS 18503-48-5) is a high-purity analytical reference standard with the molecular formula C12H14N2 and a molecular weight of 186.25 g/mol.

Structurally, 2-(Tert-butyl)quinoxaline (C12H14N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 186.25 g/mol, it falls into the medium-molecular-weight range. 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.
