Chemical Structure
Description
1-Benzyl-6-bromo-3,4-dihydronaphthalen-2(1H)-one (CAS 1246650-79-2), molecular formula C17H15BrO and molecular weight 315.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Benzyl-6-bromo-3,4-dihydronaphthalen-2(1H)-one (C17H15BrO) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 315.20 g/mol, it falls into the moderately-high-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.
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 1-Benzyl-6-bromo-3,4-dihydronaphthalen-2(1H)-one 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.
