1-(4-Isobutylphenyl)ethanol (CAS 40150-92-3, Mol. Formula C12H18O, MW 178.27) is a chiral aromatic secondary alcohol synthesised via selective reduction of 4-isobutylacetophenone, and is recognised pharmacopeially as an Ibuprofen-related impurity (Ibuprofen Impurity 32 / Imp. D2, Ph. Eur./BP designation). Structurally, it comprises a para-isobutylphenyl ring linked to a hydroxyl-bearing ethyl carbon, lending it both lipophilic character and reactive hydroxyl functionality valuable for further derivatisation. Chemicea supplies this reference compound at high analytical purity and rigorously characterises it for use in impurity profiling, method validation (AMV), and QC testing of Ibuprofen formulations within ANDA and regulatory submission workflows. Each batch is accompanied by complete analytical documentation (COA/SDS) to support traceability and compliance in pharmaceutical R&D and quality laboratories.
