Chemical Structure
Description
{[2-(1,3-Dioxo-2,3-dihydro-1h-isoindol-2-yl)ethyl]sulfanyl}methanimidamide hydrobromide (CAS 52208-11-4), molecular formula C11H11N3O2SHBr and molecular weight 330.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of {[2-(1,3-Dioxo-2,3-dihydro-1h-isoindol-2-yl)ethyl]sulfanyl}methanimidamide hydrobromide (C11H11N3O2SHBr) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 {[2-(1,3-Dioxo-2,3-dihydro-1h-isoindol-2-yl)ethyl]sulfanyl}methanimidamide hydrobromide 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.
