Chemical Structure
Description
As a certified reference material (CRM), 2,2-Bis(bromoethyl)-1,3-propanediol 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.
2,2-Bis(bromoethyl)-1,3-propanediol (CAS 34549-30-9), molecular formula C7H14Br2O2 and molecular weight 289.99 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,2-Bis(bromoethyl)-1,3-propanediol (C7H14Br2O2) is characterized by 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.
