1-[trans-7-(3-chlorophenyl)-2-oxaspiro[3.3]heptan-6-yl]ethanone CAS 2624261-52-3

Description

Compared with other compounds in its class, the molecular weight of 256.77 g/mol gives 1-[trans-7-(3-chlorophenyl)-2-oxaspiro[3.3]heptan-6-yl]ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-[trans-7-(3-chlorophenyl)-2-oxaspiro[3.3]heptan-6-yl]ethanone (CAS 2624261-52-3), a certified reference material (molecular formula C14H21ClO2, MW 256.77 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-[trans-7-(3-chlorophenyl)-2-oxaspiro[3.3]heptan-6-yl]ethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
