(1S)-2'-(Bromomethyl)-[1,1'-binaphthalene]-2-carboxaldehyde (CAS 705931-85-7), molecular formula C22H15BrO and molecular weight 375.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (1S)-2'-(Bromomethyl)-[1,1'-binaphthalene]-2-carboxaldehyde (C22H15BrO) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 375.26 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.
