3H-Pyrazolo[3,4-d]thiazole CAS 25649-12-1

Description

Compared with other compounds in its class, the molecular weight of 125.15 g/mol gives 3H-Pyrazolo[3,4-d]thiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3H-Pyrazolo[3,4-d]thiazole (CAS 25649-12-1) is a high-purity analytical reference standard with the molecular formula C4H3N3S and a molecular weight of 125.15 g/mol.

Based on its molecular formula C4H3N3S, 3H-Pyrazolo[3,4-d]thiazole contains a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 125.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 3H-Pyrazolo[3,4-d]thiazole 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.
