Description

6-(((4-((1H-Indol-1-yl)sulfonyl)phenyl)(prop-2-yn-1-yl)amino)methyl)-2-methylquinazolin-4(3H)-one (CAS 152503-91-8), molecular formula C27H22N4O3S and molecular weight 482.55 g/mol, is a CATO reference standard with documented purity and traceability.

6-(((4-((1H-Indol-1-yl)sulfonyl)phenyl)(prop-2-yn-1-yl)amino)methyl)-2-methylquinazolin-4(3H)-one (C27H22N4O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 6-(((4-((1H-Indol-1-yl)sulfonyl)phenyl)(prop-2-yn-1-yl)amino)methyl)-2-methylquinazolin-4(3H)-one 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.
