Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
5H-Benzocyclohepten-5-one, 4-hydroxy-2,3,6-trimethoxy- (6CI, 8CI, 9CI, ACI) (CAS 15795-64-9) is a high-purity analytical reference standard with the molecular formula C14H14O5 and a molecular weight of 262.26 g/mol.
The molecular framework of 5H-Benzocyclohepten-5-one, 4-hydroxy-2,3,6-trimethoxy- (6CI, 8CI, 9CI, ACI) (C14H14O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
