Description
As a certified reference material (CRM), 5-(Bromomethyl)-1,2,3,4-tetrahydronaphthalene 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.
5-(Bromomethyl)-1,2,3,4-tetrahydronaphthalene (CAS 33079-29-7) is a high-purity analytical reference standard with the molecular formula C11H13Br and a molecular weight of 225.12 g/mol.
Structurally, 5-(Bromomethyl)-1,2,3,4-tetrahydronaphthalene (C11H13Br) contains bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 225.12 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
