Description
As a certified reference material (CRM), 5-Ethyl-1,2-oxazole-4-carbaldehyde 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 5-Ethyl-1,2-oxazole-4-carbaldehyde (CAS 1368006-57-8), a certified reference material (molecular formula C6H7NO2, MW 125.13 g/mol) for analytical method development and quality control.
Structurally, 5-Ethyl-1,2-oxazole-4-carbaldehyde (C6H7NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 125.13 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
