Chemical Structure
Description
CATO supplies 3-Phenyl-5-[(phenylsulfanyl)methyl]-1,2-oxazole (CAS 478048-74-7), a certified reference material (molecular formula C16H13NOS, MW 267.35 g/mol) for analytical method development and quality control.
Structurally, 3-Phenyl-5-[(phenylsulfanyl)methyl]-1,2-oxazole (C16H13NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 267.35 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.
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), 3-Phenyl-5-[(phenylsulfanyl)methyl]-1,2-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.
