Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(6-Nitrobenzo[d]oxazol-2-yl)aniline (CAS 1107024-75-8), molecular formula C13H9N3O3 and molecular weight 255.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(6-Nitrobenzo[d]oxazol-2-yl)aniline (C13H9N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. 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 4-(6-Nitrobenzo[d]oxazol-2-yl)aniline 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.
