Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 467.64 g/mol gives Boc-C16-NHS ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Boc-C16-NHS ester (CAS 843666-34-2), molecular formula C26H45NO6 and molecular weight 467.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Boc-C16-NHS ester (C26H45NO6) is characterized by a steroid core, 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. 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 Boc-C16-NHS ester 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.
