Chemical Structure
Description
The molecular framework of 5,6,7-Trimethyl-2-(methylthio)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (C11H12N4S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5,6,7-Trimethyl-2-(methylthio)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 866041-24-9), molecular formula C11H12N4S and molecular weight 232.30 g/mol, is a CATO reference standard with documented purity and traceability.
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), 5,6,7-Trimethyl-2-(methylthio)pyrazolo[1,5-a]pyrimidine-3-carbonitrile 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.
