2-Chloro-5h,6h,7h-cyclopenta[d]pyrimidin-4-amine CAS 76780-97-7

Description

The occurrence of 2-Chloro-5h,6h,7h-cyclopenta[d]pyrimidin-4-amine is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Chloro-5h,6h,7h-cyclopenta[d]pyrimidin-4-amine (CAS 76780-97-7) is a high-purity analytical reference standard with the molecular formula C7H8ClN3 and a molecular weight of 169.61 g/mol.

Owing to a nitrile group, chlorine substitution, an aromatic ring system, 2-Chloro-5h,6h,7h-cyclopenta[d]pyrimidin-4-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
