Chemical Structure
Description
The occurrence of 3-Chloro-5-(3-chloropropyl)-10,11-dihydro-5H-dibenz[b,f]azepine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Chloro-5-(3-chloropropyl)-10,11-dihydro-5H-dibenz[b,f]azepine (CAS 51551-41-8), a certified reference material (molecular formula C17H17Cl2N, MW 306.23 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 3-Chloro-5-(3-chloropropyl)-10,11-dihydro-5H-dibenz[b,f]azepine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 manufactures 3-Chloro-5-(3-chloropropyl)-10,11-dihydro-5H-dibenz[b,f]azepine 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.
