Chemical Structure
Description
As a certified reference material (CRM), 2,5-Bis(4-methyl-5-phenyl-2-oxazolyl)pyridine 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.
CATO supplies 2,5-Bis(4-methyl-5-phenyl-2-oxazolyl)pyridine (CAS 40875-90-9), a certified reference material (molecular formula C26H20N2O2, MW 392.45 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-Bis(4-methyl-5-phenyl-2-oxazolyl)pyridine (C26H20N2O2) is characterized by a steroid core, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
