1-(2-Methyl-1,5-naphthyridin-4-yl)-3-(2-methylbenzo[d]oxazol-6-yl)urea CAS 1026047-17-5

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.

1-(2-Methyl-1,5-naphthyridin-4-yl)-3-(2-methylbenzo[d]oxazol-6-yl)urea (CAS 1026047-17-5), molecular formula C18H15N5O2 and molecular weight 333.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-(2-Methyl-1,5-naphthyridin-4-yl)-3-(2-methylbenzo[d]oxazol-6-yl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.34 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).

As a certified reference material (CRM), 1-(2-Methyl-1,5-naphthyridin-4-yl)-3-(2-methylbenzo[d]oxazol-6-yl)urea 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.
