Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-N-(5-ethyl-1,3,4-thiadiazol-2-yl)propanamide.
2-Chloro-N-(5-ethyl-1,3,4-thiadiazol-2-yl)propanamide (CAS 391864-00-9), molecular formula C7H10ClN3OS and molecular weight 219.69 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-N-(5-ethyl-1,3,4-thiadiazol-2-yl)propanamide (C7H10ClN3OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), 2-Chloro-N-(5-ethyl-1,3,4-thiadiazol-2-yl)propanamide 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.
