Chemical Structure
Description
Tetraethyl (bromomethylene)bis(phosphonate) (CAS 28845-79-6), molecular formula C9H21BrO6P2 and molecular weight 367.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tetraethyl (bromomethylene)bis(phosphonate) (C9H21BrO6P2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Tetraethyl (bromomethylene)bis(phosphonate) 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.
