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.
4-Formylphenyl 4-iodo-1-methyl-1H-pyrazole-3-carboxylate (CAS 512809-92-6), molecular formula C12H9IN2O3 and molecular weight 356.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Formylphenyl 4-iodo-1-methyl-1H-pyrazole-3-carboxylate (C12H9IN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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 4-Formylphenyl 4-iodo-1-methyl-1H-pyrazole-3-carboxylate 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.
