Chemical Structure
Description
4-Chloro-3-iodo-7-azaindole (CAS 869335-73-9) is a high-purity analytical reference standard with the molecular formula C7H4ClIN2 and a molecular weight of 278.48 g/mol.
4-Chloro-3-iodo-7-azaindole (C7H4ClIN2) contains a nitrile group, chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Chloro-3-iodo-7-azaindole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
