1-Ethyl-4-iodopyrazole CAS 172282-34-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1-Ethyl-4-iodopyrazole (CAS 172282-34-7) is a high-purity analytical reference standard with the molecular formula C5H7IN2 and a molecular weight of 222.03 g/mol.

The molecular framework of 1-Ethyl-4-iodopyrazole (C5H7IN2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 1-Ethyl-4-iodopyrazole 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.
