Chemical Structure
Description
The molecular framework of 2-(Butylsulfanyl)-4,6-dimethyl-3-(2-methylbenzenesulfonyl)pyridine (C18H23NO2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-(Butylsulfanyl)-4,6-dimethyl-3-(2-methylbenzenesulfonyl)pyridine (CAS 306978-43-8), molecular formula C18H23NO2S2 and molecular weight 349.51 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(Butylsulfanyl)-4,6-dimethyl-3-(2-methylbenzenesulfonyl)pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
