Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rel-tert-Butyl ((1R,2R)-2-((4-bromobenzyl)oxy)cyclohexyl)carbamate.
rel-tert-Butyl ((1R,2R)-2-((4-bromobenzyl)oxy)cyclohexyl)carbamate (CAS 1958100-53-2) is a high-purity analytical reference standard with the molecular formula C18H26BrNO3 and a molecular weight of 384.31 g/mol.
rel-tert-Butyl ((1R,2R)-2-((4-bromobenzyl)oxy)cyclohexyl)carbamate (C18H26BrNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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), rel-tert-Butyl ((1R,2R)-2-((4-bromobenzyl)oxy)cyclohexyl)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.
