Chemical Structure
Description
Rel-(2R,3R)-1,4-dibromobutane-2,3-diol (CAS 299-70-7), molecular formula C10H19Cl2N2O5P and molecular weight 349.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Rel-(2R,3R)-1,4-dibromobutane-2,3-diol (C10H19Cl2N2O5P) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
As a certified reference material (CRM), Rel-(2R,3R)-1,4-dibromobutane-2,3-diol 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.
