28221-20-7 P5M0O284O6 Menthyl isovalerate, (-)- Butanoic acid, 3-methyl-, (1R,2S,5R)-5-methyl-2-(1-methylethyl)cyclohexyl ester (1R-(1alpha,2beta,5alpha))-2-Isopropenyl-5-methylcyclohexyl isovalerate EINECS 248-911-4 UNII-P5M0O284O6 Validol Menthol isovalerate (CAS 28221-20-7) is a high-purity analytical reference standard with the molecular formula C15H28O2 and a molecular weight of 240.38 g/mol.

Structurally, 28221-20-7 P5M0O284O6 Menthyl isovalerate, (-)- Butanoic acid, 3-methyl-, (1R,2S,5R)-5-methyl-2-(1-methylethyl)cyclohexyl ester (1R-(1alpha,2beta,5alpha))-2-Isopropenyl-5-methylcyclohexyl isovalerate EINECS 248-911-4 UNII-P5M0O284O6 Validol Menthol isovalerate (C15H28O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 240.38 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.
