Chemical Structure
Description
CATO supplies trans-1-(bromomethyl)-2-methyl-cyclopropane (CAS 51598-33-5), a certified reference material (molecular formula C5H9Br, MW 149.03 g/mol) for analytical method development and quality control.
trans-1-(bromomethyl)-2-methyl-cyclopropane (C5H9Br) 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.
As a certified reference material (CRM), trans-1-(bromomethyl)-2-methyl-cyclopropane 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.
