4-chloro-5,5,7-trimethyl-5H,6H,7H-pyrrolo[2,3-d]pyrimidin-6-one CAS 2007917-52-2

Description

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.

4-chloro-5,5,7-trimethyl-5H,6H,7H-pyrrolo[2,3-d]pyrimidin-6-one (CAS 2007917-52-2) is a high-purity analytical reference standard with the molecular formula C9H16ClN3O and a molecular weight of 217.70 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-chloro-5,5,7-trimethyl-5H,6H,7H-pyrrolo[2,3-d]pyrimidin-6-one is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
