2-(Cyanomethyl)-6-oxo-6,7,8,9-tetrahydropyrazolo[1,5-a]quinazoline-3-carbonitrile CAS 860784-91-4 chemical structure

Description

CATO supplies 2-(Cyanomethyl)-6-oxo-6,7,8,9-tetrahydropyrazolo[1,5-a]quinazoline-3-carbonitrile (CAS 860784-91-4), a certified reference material (molecular formula C13H9N5O, MW 251.24 g/mol) for analytical method development and quality control.

The molecular framework of 2-(Cyanomethyl)-6-oxo-6,7,8,9-tetrahydropyrazolo[1,5-a]quinazoline-3-carbonitrile (C13H9N5O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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. 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), 2-(Cyanomethyl)-6-oxo-6,7,8,9-tetrahydropyrazolo[1,5-a]quinazoline-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.
