Chemical Structure
Description
The occurrence of 2-Amino-1,7-dihydro-6h-purin-6-one hydrochloride hydrate 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.
2-Amino-1,7-dihydro-6h-purin-6-one hydrochloride hydrate (CAS 6027-81-2), molecular formula C5H5N5OHClH2O and molecular weight 205.60 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H5N5OHClH2O, 2-Amino-1,7-dihydro-6h-purin-6-one hydrochloride hydrate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
