Chemical Structure

Polyhexamethylenebiguanide Hydrochloride CAS 32289-58-0 chemical structure

Description

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.

Polyhexamethylenebiguanide Hydrochloride (CAS 32289-58-0) is a high-purity analytical reference standard with the molecular formula (C8H17N5)n·HCl and a molecular weight of 219.72 g/mol.

Structurally, Polyhexamethylenebiguanide Hydrochloride ((C8H17N5)n·HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 219.72 g/mol, it falls into the medium-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.
