Chemical Structure
Description
2-(Tert-butylthio)-N-(1h-pyrazol-4-yl)acetamide (CAS 1153950-16-3), molecular formula C9H15N3OS and molecular weight 213.30 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Tert-butylthio)-N-(1h-pyrazol-4-yl)acetamide (C9H15N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
