Chemical Structure
Description
As a certified reference material (CRM), Sodium ((4-aminophenyl)sulfonyl)(5-ethyl-1,3,4-thiadiazol-2-yl)amide 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.
Sodium ((4-aminophenyl)sulfonyl)(5-ethyl-1,3,4-thiadiazol-2-yl)amide (CAS 1904-95-6) is a high-purity analytical reference standard with the molecular formula C10H11N4O2S2Na and a molecular weight of 306.33 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Sodium ((4-aminophenyl)sulfonyl)(5-ethyl-1,3,4-thiadiazol-2-yl)amide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.33 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).
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.
