Chemical Structure

(4S)-4,5-Dihydro-2,4-diphenyloxazole CAS 475571-19-8 chemical structure

Description

As a certified reference material (CRM), (4S)-4,5-Dihydro-2,4-diphenyloxazole 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.

(4S)-4,5-Dihydro-2,4-diphenyloxazole (CAS 475571-19-8) is a high-purity analytical reference standard with the molecular formula C15H13NO and a molecular weight of 223.27 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (4S)-4,5-Dihydro-2,4-diphenyloxazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 223.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
