Chemical Structure
Description
2,4-Diaminobutanoic acid hydrochloride (CAS 19391-83-4), molecular formula C4H10N2O2HCl and molecular weight 154.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4-Diaminobutanoic acid hydrochloride (C4H10N2O2HCl) is characterized by an amide 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), 2,4-Diaminobutanoic acid hydrochloride 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.
