1-((1-Cyclopentyl-1h-tetrazol-5-yl)thio)-3,3-dimethylbutan-2-one (CAS 1152624-11-7) is a high-purity analytical reference standard with the molecular formula C12H20N4OS and a molecular weight of 268.38 g/mol.
The molecular framework of 1-((1-Cyclopentyl-1h-tetrazol-5-yl)thio)-3,3-dimethylbutan-2-one (C12H20N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
