Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies (2R,4S)-2,4-diaminopentanedioic acid dihydrochloride (CAS 88155-56-0), a certified reference material (molecular formula C5H10N2O4HCl, MW 198.60 g/mol) for analytical method development and quality control.
(2R,4S)-2,4-diaminopentanedioic acid dihydrochloride (C5H10N2O4HCl) contains a carbohydrate-derived structure, an amide group, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (2R,4S)-2,4-diaminopentanedioic acid dihydrochloride 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.
