Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Midazolam-d5 (Major) Discontinued See M343003 (CAS 395067-42-2), a certified reference material (molecular formula C18H8D5ClFN3, MW 330.80 g/mol) for analytical method development and quality control.
Midazolam-d5 (Major) Discontinued See M343003 (C18H8D5ClFN3) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
As a certified reference material (CRM), Midazolam-d5 (Major) Discontinued See M343003 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.
