Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 213.11 g/mol gives 2-Bromo-p-cymene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-p-cymene (CAS 2437-76-5), molecular formula C10H13Br and molecular weight 213.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, an aromatic ring system, 2-Bromo-p-cymene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.11 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), 2-Bromo-p-cymene 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.
