Chemical Structure
Description
4-Iodo-1-Methyl-1H-pyrazole-5-carbaldehyde (CAS 959986-66-4), molecular formula C5H5IN2O and molecular weight 236.01 g/mol, is a CATO reference standard with documented purity and traceability.
4-Iodo-1-Methyl-1H-pyrazole-5-carbaldehyde (C5H5IN2O) contains an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 4-Iodo-1-Methyl-1H-pyrazole-5-carbaldehyde 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.
