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.
methyl 5-(iodomethyl)-2-methyl-4,5-dihydrofuran-3-carboxylate (CAS 128738-19-2), molecular formula C8H11IO3 and molecular weight 282.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of methyl 5-(iodomethyl)-2-methyl-4,5-dihydrofuran-3-carboxylate (C8H11IO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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 methyl 5-(iodomethyl)-2-methyl-4,5-dihydrofuran-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.
