Chemical Structure
Description
2H-Cyclopenta[d]pyrimidine (CAS 270-97-3) is a high-purity analytical reference standard with the molecular formula C7H6N2 and a molecular weight of 118.14 g/mol.
Based on its molecular formula C7H6N2, 2H-Cyclopenta[d]pyrimidine contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 118.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2H-Cyclopenta[d]pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
