WWWTP? "Third-Party" Edition

Source: Kishida Chemical
A blog buddy sent along this puckish reminder of customer perception in the crowded chemical sourcing market. Seems Oakwood Chemical, a U.S.-based supplier, recently partnered with Kishida, a Japanese fine chemicals company.

Kishida specializes in med-chem building blocks, but seems to have a problem with their structure-drawing program (right)...where did all the hydrogens go? Don't think it's just on the website - the catalog goes 50/50 for abnormal heteroatom saturation.*

Readers, am I missing something (other than those "H" atoms)? Is this part of some common fragment representation, or is it just lazy drawing?

Comments welcome.

*For a good time, check cyclobutylhydrazine dihydrochloride (PK0-13441), which seems to be missing a record five (5) hydrogens! Can anyone top that?

    Oakwood is so cheap that it's worth having to endure those painstakingly poor structures!

      I won't fight you on that point! 10 kg TEA for $150? Excellent.

    It looks to me like the structures were drawn using MDL's Symyx drawing software. It doesn't include protons unless you specifically draw them in.
