Chemical Structure
Description
As a certified reference material (CRM), 1-Bromo-2-(bromomethyl)butane 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.
1-Bromo-2-(bromomethyl)butane (CAS 28148-05-2) is a high-purity analytical reference standard with the molecular formula C5H10Br2 and a molecular weight of 229.94 g/mol.
1-Bromo-2-(bromomethyl)butane (C5H10Br2) contains 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
