The universe of possible chloro-paraffin (CP) structures is a complex one. Even the world of short-chain CPs (SCCPs) is large, containing thousands of constitutional isomers and stereoisomers. We investigated a technical SCCP mixture (Hordalub 80, Vantage Leuna, m = 56%) and found 33 CP-homologues in this material with carbon- (n) and chlorine-numbers (n) varying from 10 to 13 and 4-12, respectively.

Since 2017, short-chain CPs (SCCPs, C-C) are listed as persistent organic pollutants (POPs) in the Stockholm Convention. Technical CP mixtures contain hundreds of homologues and side products such as chlorinated olefins (COs), diolefins (CdiOs) and triolefins (CtriOs).

The mass spectrometric analysis of CPs is time-consuming and challenging, especially when interferences between CPs, their transformation products, or from the matrix are numerous. These analytical challenges and the lack of appropriate and accessible data evaluation tools are obstacles to their analysis.
