Chemical Structure
Description
The occurrence of Doxycycline-d3 is closely related to deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Doxycycline-d3 (CAS 2747918-45-0), molecular formula C22H21D3N2O8 and molecular weight 447.45 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H21D3N2O8, Doxycycline-d3 contains deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 447.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Doxycycline-d3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
