Description
As a certified reference material (CRM), Ipratropium-d7 Bromide 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.
Ipratropium-d7 Bromide (CAS CATO-CCAD303459), molecular formula C20H23D7NO3Br and molecular weight 419.41 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H23D7NO3Br, Ipratropium-d7 Bromide contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 419.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
