Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,11-diazapentacyclo[10.7.1.0^{2,10}.0^{4,9}.0^{16,20}]icosa-1(19),4(9),5,7,12(20),13,15,17-octaen-3-one (CAS 138937-84-5) is a high-purity analytical reference standard with the molecular formula C18H12N2O and a molecular weight of 272.30 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2,11-diazapentacyclo[10.7.1.0^{2,10}.0^{4,9}.0^{16,20}]icosa-1(19),4(9),5,7,12(20),13,15,17-octaen-3-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 272.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 2,11-diazapentacyclo[10.7.1.0^{2,10}.0^{4,9}.0^{16,20}]icosa-1(19),4(9),5,7,12(20),13,15,17-octaen-3-one 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.
