Chemical Structure
Description
The molecular framework of 8-Amino-5-thiaspiro[3.5]nonane-2-carboxamide hydrochloride (C9H16N2OSHCl) is characterized by an amide group, sulfur-containing functionality, 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.
8-Amino-5-thiaspiro[3.5]nonane-2-carboxamide hydrochloride (CAS 2138040-08-9) is a high-purity analytical reference standard with the molecular formula C9H16N2OSHCl and a molecular weight of 236.76 g/mol.
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), 8-Amino-5-thiaspiro[3.5]nonane-2-carboxamide 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.
