Chemical Structure

2-Phenyl-5-(1H-pyrazol-3-yl)thiazole CAS 318234-44-5 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-Phenyl-5-(1H-pyrazol-3-yl)thiazole (CAS 318234-44-5) is a high-purity analytical reference standard with the molecular formula C12H9N3S and a molecular weight of 227.28 g/mol.

The molecular framework of 2-Phenyl-5-(1H-pyrazol-3-yl)thiazole (C12H9N3S) 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), 2-Phenyl-5-(1H-pyrazol-3-yl)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.
