Sorry if you’re sick of this, but I’m having fun. You might remember my post on Havidol. (see also this follow-up). Justine Cooper (presumably) left a comment on the initial post, plus the prescribing information (PDF) has been updated. It’s still not quite right – here, apparently, is your opportunity to make it right, and get a commemorative t-shirt in the process!
Previously, the entry for Havidol gave a name that didn’t match the structure. The same was true of the molecular formula and molecular weight:
After making a couple posts to this effect, I got this follow-up:
We at HAVIDOL are flattered that you have thought to include us in your blog.
A kind professor of chemistry had advised us of the errors of our ways a few days ago. We have endeavored to make some changes to the PI on the HAVIDOL site. But we are just a bunch of lazy artists over here so it has been quite difficult to implement these changes and we are quite sure we have probably bungled it anyway. Our original chemistry specialist was discredited when it turned out that he was acutally a veterinary pathologist and not a chemist at all!
We’d like to send a HAVIDOL T-shirt ($25 value) to anyone out there interested in concocting an authentic HAVIDOL Prescribing Information PDF. It’s only 25 pages long and at a $1/page that is more than any of us have been paid since we took on this god-forsaken job of constructive parody.
Bob C. had a point when he said that most people never notice anyway. So it is our privilege to be ‘exposed’ by molecule of the day. Certainly the ad people who came to the physical exhibition never noticed.
Thanks for making us feel special.
The HAVIDOL team.
The new entry uses this structure:
Unfortunately, changing the structure a little bit means that the nomenclature, molecular formula, and molecular weight of the old one don’t quite jibe. This one has the above nomenclature, molecular formula C18H10N2 and molecular weight 254.29.
If you want a hydrochloride salt (let’s please not argue over whether it would precipitate as the mono- or di-hydrochloride), you’ll have the above structure (the two nitrogens are degenerate, so this is unambiguous), nomenclature, and have molecular formula C18H11ClN2 and molecular weight 290.75.
Please let me know if you end up writing the monograph for this! I really would do it if I had the time. C’mon, she was a good sport…
