21413-75-2 5H-Benzocyclohepten-5-one, 1-chloro-6,7,8,9-tetrahydro- CAS 21413-75-2

Description

The occurrence of 21413-75-2 5H-Benzocyclohepten-5-one, 1-chloro-6,7,8,9-tetrahydro- is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

21413-75-2 5H-Benzocyclohepten-5-one, 1-chloro-6,7,8,9-tetrahydro- (CAS 21413-75-2), molecular formula C11H11ClO and molecular weight 194.66 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 21413-75-2 5H-Benzocyclohepten-5-one, 1-chloro-6,7,8,9-tetrahydro- (C11H11ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 194.66 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.

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.

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.
