Chemical Structure

4-(Pyridin-2-yl)oxazole CAS 681135-55-7 chemical structure

Description

As a certified reference material (CRM), 4-(Pyridin-2-yl)oxazole 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.

4-(Pyridin-2-yl)oxazole (CAS 681135-55-7) is a high-purity analytical reference standard with the molecular formula C8H6N2O and a molecular weight of 146.15 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-(Pyridin-2-yl)oxazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
