Chemical Structure
Description
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 supplies 3-iodo-6-methylpyridazine (CAS 1618-47-9), a certified reference material (molecular formula C5H11IN2, MW 226.06 g/mol) for analytical method development and quality control.
Owing to iodine substitution, 3-iodo-6-methylpyridazine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 3-iodo-6-methylpyridazine 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.
