Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 1-(4-Hydroxyphenyl)-1,3,3-trimethyl-2,3-dihydro-1H-inden-5-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1-(4-Hydroxyphenyl)-1,3,3-trimethyl-2,3-dihydro-1H-inden-5-ol (CAS 109252-41-7), molecular formula C18H20O2 and molecular weight 268.35 g/mol, is a CATO reference standard with documented purity and traceability.
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.
