(5-(3,5-Dichlorobenzyl)-4-isopropyl-1-methyl-1H-imidazol-2-yl)methyl carbamate (CAS 178979-96-9), molecular formula C18H29N3O5SHCl and molecular weight 435.96 g/mol, is a CATO reference standard with documented purity and traceability.
(5-(3,5-Dichlorobenzyl)-4-isopropyl-1-methyl-1H-imidazol-2-yl)methyl carbamate (C18H29N3O5SHCl) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), (5-(3,5-Dichlorobenzyl)-4-isopropyl-1-methyl-1H-imidazol-2-yl)methyl carbamate 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.
