Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 322.19 g/mol gives 8-Benzyl-2,4-dichloro-7,8-dihydro-5H-pyrimido[4,5-c]azepin-9(6H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
8-Benzyl-2,4-dichloro-7,8-dihydro-5H-pyrimido[4,5-c]azepin-9(6H)-one (CAS 2750356-93-3) is a high-purity analytical reference standard with the molecular formula C15H13Cl2N3O and a molecular weight of 322.19 g/mol.
The molecular framework of 8-Benzyl-2,4-dichloro-7,8-dihydro-5H-pyrimido[4,5-c]azepin-9(6H)-one (C15H13Cl2N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
