Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 252.48 g/mol gives 3-Chloro-2-iodotoluene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Chloro-2-iodotoluene (CAS 5100-98-1), molecular formula C7H6ClI and molecular weight 252.48 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine/iodine substitution, an aromatic ring system, 3-Chloro-2-iodotoluene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.48 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), 3-Chloro-2-iodotoluene 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.
