Chemical Structure
Description
CATO supplies Doxycycline-d3 (CAS CATO-C4X-193110), a certified reference material (molecular formula C22H21D3N2O8, MW 447.45 g/mol) for analytical method development and quality control.
Structurally, Doxycycline-d3 (C22H21D3N2O8) contains deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.5, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 447.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.
