Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Des-(2-Methyl-6-tetrahydro-pyran-3,4-diol) Digitoxin.
Des-(2-Methyl-6-tetrahydro-pyran-3,4-diol) Digitoxin (CAS 16479-50-8), molecular formula C35H54O10 and molecular weight 634.80 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Des-(2-Methyl-6-tetrahydro-pyran-3,4-diol) Digitoxin (C35H54O10) is characterized by 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
