Chemical Structure
Description
CATO supplies 2,6-Bis((S)-4-ethyl-4,5-dihydrooxazol-2-yl)pyridine (CAS 128249-71-8), a certified reference material (molecular formula C15H19N3O2, MW 273.33 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2,6-Bis((S)-4-ethyl-4,5-dihydrooxazol-2-yl)pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,6-Bis((S)-4-ethyl-4,5-dihydrooxazol-2-yl)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.
