2,5-Dimethyl-1-(2-{5-methyl-6H,7H,8H,9H-pyrazolo[1,5-a]quinazolin-2-yl}thiophen-3-yl)-1H-pyrrole CAS 866018-12-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Dimethyl-1-(2-{5-methyl-6H,7H,8H,9H-pyrazolo[1,5-a]quinazolin-2-yl}thiophen-3-yl)-1H-pyrrole.

2,5-Dimethyl-1-(2-{5-methyl-6H,7H,8H,9H-pyrazolo[1,5-a]quinazolin-2-yl}thiophen-3-yl)-1H-pyrrole (CAS 866018-12-4), molecular formula C21H22N4S and molecular weight 362.49 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-Dimethyl-1-(2-{5-methyl-6H,7H,8H,9H-pyrazolo[1,5-a]quinazolin-2-yl}thiophen-3-yl)-1H-pyrrole (C21H22N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 2,5-Dimethyl-1-(2-{5-methyl-6H,7H,8H,9H-pyrazolo[1,5-a]quinazolin-2-yl}thiophen-3-yl)-1H-pyrrole 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.
