- Cyanuric chloride (available from Sigma-Aldrich for ~82 CAD/kg) is proposed as an inexpensive, non-controlled precursor for synthesizing acetic anhydride (Ac₂O) and acetyl chloride (AcCl) in “a few hundred gram” batches, avoiding the regulated precursors SOCl₂ and PCl₅.  
- SOCl₂ (thionyl chloride) is noted to be both a Chemical Weapons Convention (CWC) controlled substance and a DEA-listed chemical, making its procurement and shipping problematic, especially because it is a liquid.  
- Participants observe that Chinese suppliers will likely ship cyanuric chloride with minimal oversight, contrasting with the regulatory friction surrounding traditional chlorinating agents.  
- A link to Adam Marblestone’s 2019 MIT white-paper “Bottleneck Analysis for Positional Chemistry” (https://web.mit.edu/amarbles/www/docs/Bottleneck_analysis_positional_chemistry.pdf) was shared as relevant background reading for advanced molecular manufacturing strategies.  
- TechCrunch coverage of Colossal Biosciences’ $60 million Series A funding round for its “moonshot” woolly-mammoth de-extinction project was circulated, with particular attention to the participation of Cardano founder Charles Hoskinson.
