Chemical Structure
Description
n-(5-Methyl-1,3,4-thiadiazol-2(3h)-ylidene)furan-2-carboxamide (CAS 294653-40-0), molecular formula C8H7N3O2S and molecular weight 209.23 g/mol, is a CATO reference standard with documented purity and traceability.
n-(5-Methyl-1,3,4-thiadiazol-2(3h)-ylidene)furan-2-carboxamide (C8H7N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures n-(5-Methyl-1,3,4-thiadiazol-2(3h)-ylidene)furan-2-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
