Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.83 g/mol gives Diiodomethane 13C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diiodomethane 13C (CAS 86128-37-2) is a high-purity analytical reference standard with the molecular formula [13C]H2I2 and a molecular weight of 268.83 g/mol.
The molecular framework of Diiodomethane 13C ([13C]H2I2) is characterized by 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.
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 Diiodomethane 13C 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.
