Chemical Structure
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.
5-(6-Chlorooxazolo[5,4-b]pyridin-2-yl)-2-methylaniline (CAS 1354761-31-1) is a high-purity analytical reference standard with the molecular formula C13H10ClN3O and a molecular weight of 259.69 g/mol.
The molecular framework of 5-(6-Chlorooxazolo[5,4-b]pyridin-2-yl)-2-methylaniline (C13H10ClN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 5-(6-Chlorooxazolo[5,4-b]pyridin-2-yl)-2-methylaniline 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.
