(S)-2-Amino-N-isopropyl-3-methyl-N-((3-(methylthio)pyrazin-2-yl)methyl)butanamide CAS 1353997-55-3

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, (S)-2-Amino-N-isopropyl-3-methyl-N-((3-(methylthio)pyrazin-2-yl)methyl)butanamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(S)-2-Amino-N-isopropyl-3-methyl-N-((3-(methylthio)pyrazin-2-yl)methyl)butanamide (CAS 1353997-55-3), molecular formula C14H24N4OS and molecular weight 296.43 g/mol, is a CATO reference standard with documented purity and traceability.

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.
