pentane-1,4-diamine dihydrochloride CAS 89789-67-3

Description

Compared with other compounds in its class, the molecular weight of 138.64 g/mol gives pentane-1,4-diamine dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

pentane-1,4-diamine dihydrochloride (CAS 89789-67-3) is a high-purity analytical reference standard with the molecular formula C5H14N2HCl and a molecular weight of 138.64 g/mol.

Structurally, pentane-1,4-diamine dihydrochloride (C5H14N2HCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 138.64 g/mol, it falls into the low-molecular-weight range. 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.
