Chemical Structure
Description
7-(2,4-Dibromo-6-methylphenyl)-2,5,6-trimethyl-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one (CAS 291539-88-3) is a high-purity analytical reference standard with the molecular formula C16H15Br2N3O and a molecular weight of 425.12 g/mol.
The molecular framework of 7-(2,4-Dibromo-6-methylphenyl)-2,5,6-trimethyl-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one (C16H15Br2N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-(2,4-Dibromo-6-methylphenyl)-2,5,6-trimethyl-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-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.
