N-ethyl-5-(o-tolyl)-1,3,4-thiadiazol-2-amine CAS 337310-79-9

Description

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

CATO supplies N-ethyl-5-(o-tolyl)-1,3,4-thiadiazol-2-amine (CAS 337310-79-9), a certified reference material (molecular formula C11H13N3S, MW 219.31 g/mol) for analytical method development and quality control.

Structurally, N-ethyl-5-(o-tolyl)-1,3,4-thiadiazol-2-amine (C11H13N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 219.31 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-ethyl-5-(o-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.
