Chemical Structure
Description
The occurrence of 5-bromo-2-(chloromethyl)pyrimidine is closely related to chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-bromo-2-(chloromethyl)pyrimidine (CAS 944903-00-8), molecular formula C5H10BrClN2 and molecular weight 213.50 g/mol, is a CATO reference standard with documented purity and traceability.
5-bromo-2-(chloromethyl)pyrimidine (C5H10BrClN2) contains chlorine/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), 5-bromo-2-(chloromethyl)pyrimidine 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.
