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.
4-Bromo-6-chloro-2-iodo-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (CAS 1227268-75-8) is a high-purity analytical reference standard with the molecular formula C13H7BrClIN2O2S and a molecular weight of 497.53 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine/iodine substitution, 4-Bromo-6-chloro-2-iodo-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 497.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 4-Bromo-6-chloro-2-iodo-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine 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.
