Description
The occurrence of 826-73-3 5H-Benzocyclohepten-5-one, 6,7,8,9-tetrahydro- (8CI)(9CI) 6,7,8,9-Tetrahydro-5H-benzocyclohepten-5-one Benzo(b)cycloheptan-1-one 5-Benzocycloheptanone 1-Benzosuberanone alpha-Benzosuberone 1-Benzosuberone 2,3-Benzosuberone Benzsuberone EINECS 212-558-4 NSC 87961 6,7,8,9-Tetrahydrobenzobicyclohepten-5-one 6,7,8,9-Tetrahydrobenzocyclohepten-5-one is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
826-73-3 5H-Benzocyclohepten-5-one, 6,7,8,9-tetrahydro- (8CI)(9CI) 6,7,8,9-Tetrahydro-5H-benzocyclohepten-5-one Benzo(b)cycloheptan-1-one 5-Benzocycloheptanone 1-Benzosuberanone alpha-Benzosuberone 1-Benzosuberone 2,3-Benzosuberone Benzsuberone EINECS 212-558-4 NSC 87961 6,7,8,9-Tetrahydrobenzobicyclohepten-5-one 6,7,8,9-Tetrahydrobenzocyclohepten-5-one (CAS 826-73-3), molecular formula C11H18O and molecular weight 166.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 826-73-3 5H-Benzocyclohepten-5-one, 6,7,8,9-tetrahydro- (8CI)(9CI) 6,7,8,9-Tetrahydro-5H-benzocyclohepten-5-one Benzo(b)cycloheptan-1-one 5-Benzocycloheptanone 1-Benzosuberanone alpha-Benzosuberone 1-Benzosuberone 2,3-Benzosuberone Benzsuberone EINECS 212-558-4 NSC 87961 6,7,8,9-Tetrahydrobenzobicyclohepten-5-one 6,7,8,9-Tetrahydrobenzocyclohepten-5-one (C11H18O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 826-73-3 5H-Benzocyclohepten-5-one, 6,7,8,9-tetrahydro- (8CI)(9CI) 6,7,8,9-Tetrahydro-5H-benzocyclohepten-5-one Benzo(b)cycloheptan-1-one 5-Benzocycloheptanone 1-Benzosuberanone alpha-Benzosuberone 1-Benzosuberone 2,3-Benzosuberone Benzsuberone EINECS 212-558-4 NSC 87961 6,7,8,9-Tetrahydrobenzobicyclohepten-5-one 6,7,8,9-Tetrahydrobenzocyclohepten-5-one 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.
