Chemical Structure
Description
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.
2-((3AR,7aS)-2,2-dimethyl-3a,7a-dihydrobenzo[d][1,3]dioxol-5-yl)propan-2-ol (CAS 1998128-16-7) is a high-purity analytical reference standard with the molecular formula C12H18O3 and a molecular weight of 210.27 g/mol.
Structurally, 2-((3AR,7aS)-2,2-dimethyl-3a,7a-dihydrobenzo[d][1,3]dioxol-5-yl)propan-2-ol (C12H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 210.27 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.
