Chemical Structure

(S,R,S,S)-Orlistat CAS 111466-63-8 chemical structure

Description

(S,R,S,S)-Orlistat (CAS 111466-63-8) is a high-purity analytical reference standard with the molecular formula C29H53NO5 and a molecular weight of 495.73 g/mol.

Based on its molecular formula C29H53NO5, (S,R,S,S)-Orlistat contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 495.73 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).

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.
