Chemical Structure

N-ethyl-5-(p-tolyl)-1,3,4-thiadiazol-2-amine CAS 488794-36-1 chemical structure

Description

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.

N-ethyl-5-(p-tolyl)-1,3,4-thiadiazol-2-amine (CAS 488794-36-1) is a high-purity analytical reference standard with the molecular formula C11H13N3S and a molecular weight of 219.31 g/mol.

The molecular framework of N-ethyl-5-(p-tolyl)-1,3,4-thiadiazol-2-amine (C11H13N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), N-ethyl-5-(p-tolyl)-1,3,4-thiadiazol-2-amine 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.
