Compared with other compounds in its class, the molecular weight of 399.52 g/mol gives (-)-3-Methoxy Butorphanol 6-Ethylene Ketal distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(-)-3-Methoxy Butorphanol 6-Ethylene Ketal (CAS 67753-31-5), molecular formula C24H33NO4 and molecular weight 399.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (-)-3-Methoxy Butorphanol 6-Ethylene Ketal (C24H33NO4) is characterized by a flavonoid 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).
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 (-)-3-Methoxy Butorphanol 6-Ethylene Ketal 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.
