Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 185.02 g/mol gives H-Dap-OH.HBr distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
H-Dap-OH.HBr (CAS 1186-65-8), molecular formula C3H8N2O2HBr and molecular weight 185.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of H-Dap-OH.HBr (C3H8N2O2HBr) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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), H-Dap-OH.HBr 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.
