Chemical Structure
Description
5-[(4-butylphenyl)amino]-1,3,4-thiadiazole-2-thiol (CAS 750613-93-5) is a high-purity analytical reference standard with the molecular formula C12H15N3S2 and a molecular weight of 265.40 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 5-[(4-butylphenyl)amino]-1,3,4-thiadiazole-2-thiol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 265.40 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), 5-[(4-butylphenyl)amino]-1,3,4-thiadiazole-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.
