2-(1,5-Dimethyl-1H-pyrazol-4-ylimino)-thiazolidin-4-one CAS 1003993-33-6 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.

2-(1,5-Dimethyl-1H-pyrazol-4-ylimino)-thiazolidin-4-one (CAS 1003993-33-6) is a high-purity analytical reference standard with the molecular formula C8H10N4OS and a molecular weight of 210.26 g/mol.

The molecular framework of 2-(1,5-Dimethyl-1H-pyrazol-4-ylimino)-thiazolidin-4-one (C8H10N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 2-(1,5-Dimethyl-1H-pyrazol-4-ylimino)-thiazolidin-4-one 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.
