3-Amino-5-chloropyrazine-2(1H)-thione, sodium salt CAS 1801694-21-2

Description

Compared with other compounds in its class, the molecular weight of 184.60 g/mol gives 3-Amino-5-chloropyrazine-2(1H)-thione, sodium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Amino-5-chloropyrazine-2(1H)-thione, sodium salt (CAS 1801694-21-2) is a high-purity analytical reference standard with the molecular formula C4H4ClN3SNa and a molecular weight of 184.60 g/mol.

The molecular framework of 3-Amino-5-chloropyrazine-2(1H)-thione, sodium salt (C4H4ClN3SNa) is characterized by a salt form, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
