**Original comment by Daniel Lowe (Bitbucket: [dan2097](https://bitbucket.org/dan2097), GitHub: [dan2097](https://github.com/dan2097)).** ---------------------------------------- I really hate biochemical nomenclature. Choline phosphate/sulfate for comparison typically refers to the ester

There's unfortunately ambiguity between common usage and IUPAC nomenclature. In common usage alcohols and groups like nitrate and acetate can implicitly be connected with loss of water. This particular instance...

I can only find one name on the internet that has this mistake: S-(+)-N2-Methyltryptophan methyl ester, this sounds far more amenable to a dictionary based solution. OPSIN does not aim...

Thanks for pointing this out, I'm just thinking about the best way of implementing this. I can find one counterexample, mercury(I) hydride, which more typically is HgH, but indeed the...

If I'm understanding correctly, ChemSrc also has the "wrong" structure? (extra nitrogen) I don't think it's possible for OPSIN to ignore the extra nitrogen without the potential for breaking other...

**Original comment by DK (Bitbucket: [anonopsin](https://bitbucket.org/anonopsin), ).** ---------------------------------------- Yes - apologies for not being clearer.

**Original comment by DK (Bitbucket: [anonopsin](https://bitbucket.org/anonopsin), ).** ---------------------------------------- I take it that this depends on the Indigo toolkit? Edit: It appears so: https://lifescience.opensource.epam.com/indigo/options/rendering-options.html#render-atom-ids-visible

**Original comment by Daniel Lowe (Bitbucket: [dan2097](https://bitbucket.org/dan2097), GitHub: [dan2097](https://github.com/dan2097)).** ---------------------------------------- Yes, OPSIN converts the chemical name to a structure, then the Indigo toolkit converts this to a depiction. Source code...

The fix to that issue means that "Disodium bis(4-chloro-3-sulfophenyl)sulfone salt" will now give...
