Description
782475-35-8 3-(2-(2-(2-Bromoethoxy)ethoxy)ethoxy)propanoic acid MFCD22574820 Bromo-PEG3-acid (CAS 782475-35-8) is a high-purity analytical reference standard with the molecular formula C9H17BrO5 and a molecular weight of 285.13 g/mol.
782475-35-8 3-(2-(2-(2-Bromoethoxy)ethoxy)ethoxy)propanoic acid MFCD22574820 Bromo-PEG3-acid (C9H17BrO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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), 782475-35-8 3-(2-(2-(2-Bromoethoxy)ethoxy)ethoxy)propanoic acid MFCD22574820 Bromo-PEG3-acid 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.
