Chemical Structure
Description
The occurrence of (R)-2-Aminobut-3-ynoic acid hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (R)-2-Aminobut-3-ynoic acid hydrochloride (CAS 1956436-19-3), a certified reference material (molecular formula C4H5NO2HCl, MW 135.55 g/mol) for analytical method development and quality control.
(R)-2-Aminobut-3-ynoic acid hydrochloride (C4H5NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
As a certified reference material (CRM), (R)-2-Aminobut-3-ynoic 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.
