CATO supplies 33452-18-5 5-Iodo-1-methyl-1H-tetrazole DTXSID20557682 (CAS 33452-18-5), a certified reference material (molecular formula C2H3IN4, MW 209.98 g/mol) for analytical method development and quality control.
The molecular framework of 33452-18-5 5-Iodo-1-methyl-1H-tetrazole DTXSID20557682 (C2H3IN4) is characterized by a nitrile group, iodine 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. 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.
