Chemical Structure
Description
The molecular framework of 291-21-4 1,3,5-Trithiacyclohexane 1,3,5-Trithiane s-Trithiane 5-19-09-00105 (Beilstein Handbook Reference) AI3-09774 BRN 0079834 EINECS 206-029-7 Formaldehyde, thio-, trimer NSC 1937 Thioform [Czech] Trimethylene trisulfide Trimethylentrisulfid [Czech] sym-Trithian [Czech] Trithioformaldehyde sym-Trithian Thioform Trimethylentrisulfid (C3H6S3) is characterized by sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
