CATO supplies [Dha7]-Microcystin-LR (NRC Certified Calibration Solution)Concentration: 9.58 μmol/L of dmMCLR in aqueous Methanol (1:1, v/v) (CAS 134842-07-2), a certified reference material (molecular formula C48H72N10O12, MW 981.15 g/mol) for analytical method development and quality control.
Structurally, [Dha7]-Microcystin-LR (NRC Certified Calibration Solution)Concentration: 9.58 μmol/L of dmMCLR in aqueous Methanol (1:1, v/v) (C48H72N10O12) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 981.15 g/mol, it falls into the 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).
As a certified reference material (CRM), [Dha7]-Microcystin-LR (NRC Certified Calibration Solution)Concentration: 9.58 μmol/L of dmMCLR in aqueous Methanol (1:1, v/v) 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.
