Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 322.08 g/mol gives 5,7-Dimethyl-1,3-dibromoadamantane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5,7-Dimethyl-1,3-dibromoadamantane (CAS 21912-23-2), a certified reference material (molecular formula C12H18Br2, MW 322.08 g/mol) for analytical method development and quality control.
Structurally, 5,7-Dimethyl-1,3-dibromoadamantane (C12H18Br2) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 322.08 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 5,7-Dimethyl-1,3-dibromoadamantane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
