Chemical Structure
Description
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.
1-(2-Mercaptoethyl)guanidine sulfate (CAS 3979-00-8) is a high-purity analytical reference standard with the molecular formula C3H9N3SH2O4S and a molecular weight of 217.26 g/mol.
Structurally, 1-(2-Mercaptoethyl)guanidine sulfate (C3H9N3SH2O4S) contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage. 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 217.26 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
