Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 390.52 g/mol gives SU 1498 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
SU 1498 (CAS 168835-82-3), molecular formula C25H30N2O2 and molecular weight 390.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of SU 1498 (C25H30N2O2) 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 its high hydrophobicity (logP), 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).
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 SU 1498 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.
