Chemical Structure
Description
As a certified reference material (CRM), 2-(3,4-dimethoxyphenyl)-1,3-benzoxazole 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.
2-(3,4-dimethoxyphenyl)-1,3-benzoxazole (CAS 92552-99-3) is a high-purity analytical reference standard with the molecular formula C15H13NO3 and a molecular weight of 255.27 g/mol.
The molecular framework of 2-(3,4-dimethoxyphenyl)-1,3-benzoxazole (C15H13NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
