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.

35250-53-4 F7I6G0E56F Pyrazineethanethiol Ethanethiol, 2-pyrazinyl- 2-Pyrazineethanethiol 5-23-11-00173 (Beilstein Handbook Reference) BRN 0774932 FEMA 3230 FEMA No. 3230 Pyrazinyl ethanethiol 2-Pyrazinylethanethiol 2-Pyrazinylethylmercaptan UNII-F7I6G0E56F (CAS 35250-53-4), molecular formula C6H14N2S and molecular weight 146.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H14N2S, 35250-53-4 F7I6G0E56F Pyrazineethanethiol Ethanethiol, 2-pyrazinyl- 2-Pyrazineethanethiol 5-23-11-00173 (Beilstein Handbook Reference) BRN 0774932 FEMA 3230 FEMA No. 3230 Pyrazinyl ethanethiol 2-Pyrazinylethanethiol 2-Pyrazinylethylmercaptan UNII-F7I6G0E56F contains sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 146.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
