new legal bk-4

[Tyram]

Greetings, dear participants of the forum. Due to the ban on the bk-4 precursor for the synthesis of 4-mmc, legal substitutes such as 2-(1-bromoethyl)-4-methyl-2-(4-methylphenyl)-1,3-dioxolane have emerged. I don't know the CAS number. Does anyone know about this reagent and those who produce its legal analogues?

this site i found has that name but in a different order [1,3-Dioxolane, 2-(1-bromoethyl)-2-(4-methylphenyl)-]. it also has a CAS number: 91306-36-4. the structure looks kind of different, but the only other search results i could find (including pubchem) had a different name and no CAS number. i really hope i could help
