Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(5-Cyclopropyl-1,3,4-thiadiazol-2-yl)-4-methylbenzamide.

N-(5-Cyclopropyl-1,3,4-thiadiazol-2-yl)-4-methylbenzamide (CAS 556040-44-9), molecular formula C13H13N3OS and molecular weight 259.33 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-(5-Cyclopropyl-1,3,4-thiadiazol-2-yl)-4-methylbenzamide (C13H13N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 259.33 g/mol, it falls into the medium-molecular-weight range. 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), N-(5-Cyclopropyl-1,3,4-thiadiazol-2-yl)-4-methylbenzamide 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.
