Description
As a certified reference material (CRM), (2-{[3-Iodo-1-(tetrahydropyran-2-yl)-1H-pyrazol-4-ylmethyl]-methylamino}-ethyl)-methyl-carbamic acid tert-butyl ester 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.
(2-{[3-Iodo-1-(tetrahydropyran-2-yl)-1H-pyrazol-4-ylmethyl]-methylamino}-ethyl)-methyl-carbamic acid tert-butyl ester (CAS 1782069-01-5) is a high-purity analytical reference standard with the molecular formula C18H31IN4O3 and a molecular weight of 478.37 g/mol.
(2-{[3-Iodo-1-(tetrahydropyran-2-yl)-1H-pyrazol-4-ylmethyl]-methylamino}-ethyl)-methyl-carbamic acid tert-butyl ester (C18H31IN4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
