Description
As a certified reference material (CRM), 2-(Methylsulfonyl)-5-phenyl-1,3,4-oxadiazole 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.
2-(Methylsulfonyl)-5-phenyl-1,3,4-oxadiazole (CAS 23767-32-0) is a high-purity analytical reference standard with the molecular formula C9H8N2O3S and a molecular weight of 224.24 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(Methylsulfonyl)-5-phenyl-1,3,4-oxadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.24 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.
