Chemical Structure

2-Amino-6,7-dihydro-5H-cyclopenta[d]pyrimidine CAS 108990-72-3 chemical structure

Description

2-Amino-6,7-dihydro-5H-cyclopenta[d]pyrimidine (CAS 108990-72-3) is a high-purity analytical reference standard with the molecular formula C7H9N3 and a molecular weight of 135.17 g/mol.

The molecular framework of 2-Amino-6,7-dihydro-5H-cyclopenta[d]pyrimidine (C7H9N3) is characterized by a nitrile group, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 2-Amino-6,7-dihydro-5H-cyclopenta[d]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
