Chemical Structure
Description
The occurrence of Dimethyl 2,2'-(adamantane-1,3-diyl)bis(2-bromoacetate) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dimethyl 2,2'-(adamantane-1,3-diyl)bis(2-bromoacetate) (CAS 202534-05-2), molecular formula C16H22Br2O4 and molecular weight 438.15 g/mol, is a CATO reference standard with documented purity and traceability.
Dimethyl 2,2'-(adamantane-1,3-diyl)bis(2-bromoacetate) (C16H22Br2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Dimethyl 2,2'-(adamantane-1,3-diyl)bis(2-bromoacetate) 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.
