Chemical Structure
Description
2-(Isopropylthio)aniline (CAS 6397-33-7), molecular formula C9H13NS and molecular weight 167.27 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Isopropylthio)aniline (C9H13NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
