Chemical Structure

7-Methyl-1-tosyl-3,4-dihydro-1H-benzo[b]azepin-5(2H)-one CAS 1118507-77-9 chemical structure

Description

The molecular framework of 7-Methyl-1-tosyl-3,4-dihydro-1H-benzo[b]azepin-5(2H)-one (C18H19NO3S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

7-Methyl-1-tosyl-3,4-dihydro-1H-benzo[b]azepin-5(2H)-one (CAS 1118507-77-9) is a high-purity analytical reference standard with the molecular formula C18H19NO3S and a molecular weight of 329.41 g/mol.

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