Chemical Structure
Description
CATO supplies 1,1,3-Tribromoacetone (CAS 3475-39-6), a certified reference material (molecular formula C3H3Br3O, MW 294.77 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, bromine substitution, 1,1,3-Tribromoacetone is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1,1,3-Tribromoacetone 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.
