(E)-4-(2-benzylidenehydrazinyl)-6-isopropylthieno[2,3-d]pyrimidine CAS 439689-85-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-(2-benzylidenehydrazinyl)-6-isopropylthieno[2,3-d]pyrimidine.

CATO supplies (E)-4-(2-benzylidenehydrazinyl)-6-isopropylthieno[2,3-d]pyrimidine (CAS 439689-85-7), a certified reference material (molecular formula C16H16N4S, MW 296.39 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, (E)-4-(2-benzylidenehydrazinyl)-6-isopropylthieno[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (E)-4-(2-benzylidenehydrazinyl)-6-isopropylthieno[2,3-d]pyrimidine 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.
