Description
As a certified reference material (CRM), 5-Iodo-2,3,3-trimethyl-3H-indole 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.
CATO supplies 5-Iodo-2,3,3-trimethyl-3H-indole (CAS 54136-25-3), a certified reference material (molecular formula C11H12IN, MW 285.12 g/mol) for analytical method development and quality control.
5-Iodo-2,3,3-trimethyl-3H-indole (C11H12IN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
