Chemical Structure
Description
The occurrence of (3S)-3-amino-2,3-dihydro-1H-inden-5-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.
(3S)-3-amino-2,3-dihydro-1H-inden-5-ol hydrochloride (CAS 1821520-81-3), molecular formula C9H17NOHCl and molecular weight 191.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3S)-3-amino-2,3-dihydro-1H-inden-5-ol hydrochloride (C9H17NOHCl) 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.
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), (3S)-3-amino-2,3-dihydro-1H-inden-5-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.
