Chemical Structure
Description
The occurrence of (S)-1-aminopent-4-yn-2-ol hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (S)-1-aminopent-4-yn-2-ol hydrochloride (CAS 1234692-74-0), a certified reference material (molecular formula C5H9NOHCl, MW 135.59 g/mol) for analytical method development and quality control.
The molecular framework of (S)-1-aminopent-4-yn-2-ol hydrochloride (C5H9NOHCl) is characterized by an amide 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), (S)-1-aminopent-4-yn-2-ol 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.
