Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 197.62 g/mol gives H-Asp(OMe)-OMe · HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
H-Asp(OMe)-OMe · HCl (CAS 32213-95-9) is a high-purity analytical reference standard with the molecular formula C6H11NO4HCl and a molecular weight of 197.62 g/mol.
Based on its molecular formula C6H11NO4HCl, H-Asp(OMe)-OMe · HCl contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 197.62 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
