Chemical Structure

(S,R,R,R)-Orlistat CAS 111466-61-6 chemical structure

Description

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.

(S,R,R,R)-Orlistat (CAS 111466-61-6), molecular formula C29H53NO5 and molecular weight 495.73 g/mol, is a CATO reference standard with documented purity and traceability.

(S,R,R,R)-Orlistat (C29H53NO5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; 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).

CATO manufactures (S,R,R,R)-Orlistat 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.
