Chemical Structure

1-(2-Mercaptoethyl)guanidine hydrochloride CAS 19767-44-3 chemical structure

Description

1-(2-Mercaptoethyl)guanidine hydrochloride (CAS 19767-44-3), molecular formula C3H10N3SCl and molecular weight 155.64 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(2-Mercaptoethyl)guanidine hydrochloride (C3H10N3SCl) contains sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 155.64 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.

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.
