Chemical Structure
Description
The occurrence of 5-(5-Methyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-1,3,4-oxadiazole-2-thiol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-(5-Methyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-1,3,4-oxadiazole-2-thiol (CAS 857041-72-6), a certified reference material (molecular formula C11H12N2OS2, MW 252.36 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-(5-Methyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-1,3,4-oxadiazole-2-thiol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 252.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 5-(5-Methyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-1,3,4-oxadiazole-2-thiol 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.
