Chemical Structure
Description
The occurrence of 1-Dehydroxy-1-Dehyro-Fexofenadine-d6 Methyl Ester is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Dehydroxy-1-Dehyro-Fexofenadine-d6 Methyl Ester (CAS 1795031-46-7), molecular formula C33H31D6NO3 and molecular weight 501.69 g/mol, is a CATO reference standard with documented purity and traceability.
1-Dehydroxy-1-Dehyro-Fexofenadine-d6 Methyl Ester (C33H31D6NO3) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
