4-((4-Methylbenzyl)thio)-2-(thiophen-2-yl)pyrazolo[1,5-a]pyrazine CAS 1040663-10-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((4-Methylbenzyl)thio)-2-(thiophen-2-yl)pyrazolo[1,5-a]pyrazine.

CATO supplies 4-((4-Methylbenzyl)thio)-2-(thiophen-2-yl)pyrazolo[1,5-a]pyrazine (CAS 1040663-10-2), a certified reference material (molecular formula C18H15N3S2, MW 337.46 g/mol) for analytical method development and quality control.

The molecular framework of 4-((4-Methylbenzyl)thio)-2-(thiophen-2-yl)pyrazolo[1,5-a]pyrazine (C18H15N3S2) 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).

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), 4-((4-Methylbenzyl)thio)-2-(thiophen-2-yl)pyrazolo[1,5-a]pyrazine 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.
