Chemical Structure
Description
Iodomethane-d (CAS 992-96-1), molecular formula CH2DI and molecular weight 142.95 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, iodine substitution, Iodomethane-d is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.95 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Iodomethane-d 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.
