Chemical Structure

1,3,3,4,4-Pentamethyl-2-acetyl-1-cyclopentene CAS 13144-88-2 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.

CATO supplies 1,3,3,4,4-Pentamethyl-2-acetyl-1-cyclopentene (CAS 13144-88-2), a certified reference material (molecular formula C12H20O, MW 180.29 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H20O, 1,3,3,4,4-Pentamethyl-2-acetyl-1-cyclopentene contains a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 180.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
