Chemical Structure
Description
The occurrence of 3-[(2,5-Dimethylphenyl)methyl]-3,21-diazapentacyclo[11.8.0.0^{2,10}.0^{4,9}.0^{15,20}]henicosa-1(21),2(10),4(9),5,7,13,15(20),16,18-nonaene is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-[(2,5-Dimethylphenyl)methyl]-3,21-diazapentacyclo[11.8.0.0^{2,10}.0^{4,9}.0^{15,20}]henicosa-1(21),2(10),4(9),5,7,13,15(20),16,18-nonaene (CAS 860644-58-2) is a high-purity analytical reference standard with the molecular formula C28H24N2 and a molecular weight of 388.50 g/mol.
The molecular framework of 3-[(2,5-Dimethylphenyl)methyl]-3,21-diazapentacyclo[11.8.0.0^{2,10}.0^{4,9}.0^{15,20}]henicosa-1(21),2(10),4(9),5,7,13,15(20),16,18-nonaene (C28H24N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 3-[(2,5-Dimethylphenyl)methyl]-3,21-diazapentacyclo[11.8.0.0^{2,10}.0^{4,9}.0^{15,20}]henicosa-1(21),2(10),4(9),5,7,13,15(20),16,18-nonaene 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.
