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.
3,4-Dihydro-2H-benzo[b][1,4]dioxepine-7-carboxamide (CAS 950444-42-5), molecular formula C10H11NO3 and molecular weight 193.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4-Dihydro-2H-benzo[b][1,4]dioxepine-7-carboxamide (C10H11NO3) is characterized by an amino-acid-derived structure, an amide 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.
CATO manufactures 3,4-Dihydro-2H-benzo[b][1,4]dioxepine-7-carboxamide 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.
