Chemical Structure

7-Bromo-2-chloro-5-trityl-5H-pyrrolo[2,3-b]pyrazine CAS 1509941-36-9 chemical structure

Description

The occurrence of 7-Bromo-2-chloro-5-trityl-5H-pyrrolo[2,3-b]pyrazine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Bromo-2-chloro-5-trityl-5H-pyrrolo[2,3-b]pyrazine (CAS 1509941-36-9) is a high-purity analytical reference standard with the molecular formula C25H17BrClN3 and a molecular weight of 474.78 g/mol.

Structurally, 7-Bromo-2-chloro-5-trityl-5H-pyrrolo[2,3-b]pyrazine (C25H17BrClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 474.78 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
