Chemical Structure
Description
4-Chloro-6-methyl-7-phenyl-7H-pyrrolo[2,3-d]pyrimidine (CAS 35808-71-0) is a high-purity analytical reference standard with the molecular formula C13H10ClN3 and a molecular weight of 243.69 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-Chloro-6-methyl-7-phenyl-7H-pyrrolo[2,3-d]pyrimidine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 243.69 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).
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.
