Chemical Structure
Description
CATO supplies 3-(Benzo[d]oxazol-2-yl)benzaldehyde (CAS 141581-19-3), a certified reference material (molecular formula C14H9NO2, MW 223.23 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Benzo[d]oxazol-2-yl)benzaldehyde (C14H9NO2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 3-(Benzo[d]oxazol-2-yl)benzaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
