Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 574.78 g/mol gives Carbenoxolone-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Carbenoxolone-d4 (CAS 5697-56-3 (Unlabeled)), molecular formula C34H46D4O7 and molecular weight 574.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Carbenoxolone-d4 (C34H46D4O7) is characterized by deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
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 Carbenoxolone-d4 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.
