Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution, 7-benzyl-5-bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 7-benzyl-5-bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine (CAS 1244855-70-6), a certified reference material (molecular formula C13H9BrClN3, MW 322.59 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
