Chemical Structure

2-(isopropylsulfinyl)aniline CAS 1251360-65-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 183.27 g/mol gives 2-(isopropylsulfinyl)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, 2-(isopropylsulfinyl)aniline (CAS 1251360-65-2, C9H13NOS) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-(isopropylsulfinyl)aniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures 2-(isopropylsulfinyl)aniline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
