Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Bromo-PEG8-Boc (CAS 1623792-00-6), a certified reference material (molecular formula C23H45BrO10, MW 561.50 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Bromo-PEG8-Boc is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 561.50 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.
As a certified reference material (CRM), Bromo-PEG8-Boc 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.
