The occurrence of Dodecylbenzene Sulfonic Acid Potassium Salt (Mixture of Isomers) is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dodecylbenzene Sulfonic Acid Potassium Salt (Mixture of Isomers) (CAS 27177-77-1), molecular formula C18H29O3SK and molecular weight 364.58 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dodecylbenzene Sulfonic Acid Potassium Salt (Mixture of Isomers) (C18H29O3SK) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 364.58 g/mol, it falls into the moderately-high-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.
As a certified reference material (CRM), Dodecylbenzene Sulfonic Acid Potassium Salt (Mixture of Isomers) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
