Description

2033-45-6 Pyrazole, 3,5-dimethyl-4-iodo- 5-23-05-00159 (Beilstein Handbook Reference) BRN 0108535 3,5-Dimethyl-4-iodopyrazole NSC 100887 (CAS 2033-45-6) is a high-purity analytical reference standard with the molecular formula C5H11IN2 and a molecular weight of 226.06 g/mol.

The molecular framework of 2033-45-6 Pyrazole, 3,5-dimethyl-4-iodo- 5-23-05-00159 (Beilstein Handbook Reference) BRN 0108535 3,5-Dimethyl-4-iodopyrazole NSC 100887 (C5H11IN2) is characterized by 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.

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.

As a certified reference material (CRM), 2033-45-6 Pyrazole, 3,5-dimethyl-4-iodo- 5-23-05-00159 (Beilstein Handbook Reference) BRN 0108535 3,5-Dimethyl-4-iodopyrazole NSC 100887 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.
