Chemical Structure

S-Benzyl-N-Stearoyl-L-cysteine CAS 40379-70-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

S-Benzyl-N-Stearoyl-L-cysteine (CAS 40379-70-2), molecular formula C28H47NO3S and molecular weight 477.74 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C28H47NO3S, S-Benzyl-N-Stearoyl-L-cysteine contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 477.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
