Chemical Structure
Description
The occurrence of (S)-1,2-Diaminopropane Dihydrochloride is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-1,2-Diaminopropane Dihydrochloride (CAS 19777-66-3), molecular formula C3H10N2HCl and molecular weight 110.59 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-1,2-Diaminopropane Dihydrochloride (C3H10N2HCl) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
