Chemical Structure

2-Ethyl-2-oxazoline CAS 10431-98-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 99.13 g/mol gives 2-Ethyl-2-oxazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Ethyl-2-oxazoline (CAS 10431-98-8), molecular formula C5H9NO and molecular weight 99.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 2-Ethyl-2-oxazoline is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 99.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 2-Ethyl-2-oxazoline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
