Description
CATO supplies 5-Bromo-3-methyl-2-(methylsulfonyl)-7-((2-(trimethylsilyl)ethoxy)methyl)-3,7-dihydro-4H-pyrrolo[2,3-d]pyrimidin-4-one (CAS 2055938-36-6), a certified reference material (molecular formula C14H22BrN3O4SSi, MW 436.40 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-3-methyl-2-(methylsulfonyl)-7-((2-(trimethylsilyl)ethoxy)methyl)-3,7-dihydro-4H-pyrrolo[2,3-d]pyrimidin-4-one (C14H22BrN3O4SSi) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-Bromo-3-methyl-2-(methylsulfonyl)-7-((2-(trimethylsilyl)ethoxy)methyl)-3,7-dihydro-4H-pyrrolo[2,3-d]pyrimidin-4-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.
