Chemical Structure
Description
The occurrence of 2,3-Dibromo-2-methylpropanenitrile is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,3-Dibromo-2-methylpropanenitrile (CAS 28786-90-5), molecular formula C4H5Br2N and molecular weight 226.90 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Dibromo-2-methylpropanenitrile (C4H5Br2N) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; 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), 2,3-Dibromo-2-methylpropanenitrile 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.
