Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 317.42 g/mol gives (3R,11bR)-Tetrabenazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(3R,11bR)-Tetrabenazine (CAS 1026016-83-0) is a high-purity analytical reference standard with the molecular formula C19H27NO3 and a molecular weight of 317.42 g/mol.
The molecular framework of (3R,11bR)-Tetrabenazine (C19H27NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 (3R,11bR)-Tetrabenazine 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.
