The molecular framework of H92E6QA4FV 557-05-1 Octadecanoic acid, zinc salt Zinc octadecanoate Zinc stearate Zinc stearate [USP] Octadecanoic acid, zinc salt (2:1) Stearic acid, zinc salt (8CI) Zinc distearate, pure Zinc distearate AI3-00388 Caswell No. 926 Coad Dermarone Dibasic zinc stearate EINECS 209-151-9 EPA Pesticide Chemical Code 077002 HSDB 212 Hydense Hytech Mathe Metallac Metasap 576 NSC 25957 Petrac ZN-41 Stavinor ZN-E Stearates Stearic acid, zinc salt Synpro stearate Synpro stearate (VAN) Talculin Z Unichem ZS Witco Zinc Stearate USP Zinc stearate W. S Zn Stearate Zink distearat Zinci stearas Zincum stearinicum UNII-H92E6QA4FV EC 209-151-9 Zinc stearate, respirable fraction Zinc stearate, total dust (C36H70O4Zn) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
