Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 335.21 g/mol gives Bromo-PEG4-MS distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bromo-PEG4-MS (CAS 2167807-41-0) is a high-purity analytical reference standard with the molecular formula C9H19BrO6S and a molecular weight of 335.21 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Bromo-PEG4-MS is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.21 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.
CATO manufactures Bromo-PEG4-MS under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
