Chemical Structure
Description
3-Cyclopropyl-3,4-dihydro-2H-1,3-benzothiazine-2,4-dione (CAS 338401-64-2) is a high-purity analytical reference standard with the molecular formula C11H9NO2S and a molecular weight of 219.26 g/mol.
The molecular framework of 3-Cyclopropyl-3,4-dihydro-2H-1,3-benzothiazine-2,4-dione (C11H9NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-Cyclopropyl-3,4-dihydro-2H-1,3-benzothiazine-2,4-dione 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.
