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.
CATO supplies 8-Chloro-2,3,4,5-tetrahydro-1H-1-benzazepine-2,5-dione (CAS 87379-41-7), a certified reference material (molecular formula C10H8ClNO2, MW 209.63 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 8-Chloro-2,3,4,5-tetrahydro-1H-1-benzazepine-2,5-dione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 8-Chloro-2,3,4,5-tetrahydro-1H-1-benzazepine-2,5-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.
