Chemical Structure

1-Butyl-4-iodo-5-methyl-1H-pyrazole CAS 1354705-47-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 264.11 g/mol gives 1-Butyl-4-iodo-5-methyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Butyl-4-iodo-5-methyl-1H-pyrazole (CAS 1354705-47-7), a certified reference material (molecular formula C8H13IN2, MW 264.11 g/mol) for analytical method development and quality control.

The molecular framework of 1-Butyl-4-iodo-5-methyl-1H-pyrazole (C8H13IN2) 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.

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.

CATO manufactures 1-Butyl-4-iodo-5-methyl-1H-pyrazole 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.
