 ::Hi LamasUI.  The red Xs indicate that the values that have changed since they were verified by editors that are working on Wikipedia:WikiProject Chemicals/Chembox validation.  I think I have now verified the data and made the changes that have restored the green check marks, but it's been awhile since I've done that before so hopefully it will remain verified.  As for the tag on the top of the article, that was placed by me.  I put it there because I think the article relies to heavily on press releases.  Generally, if information is not available from any source except through press releases, that information probably isn't appropriate for the article.  If independent sources are reporting on or commenting on such information then it may be notable enough to include in the article.  Also, I suggest you have a look at Wikipedia's conflict of interest policy which I suspect may apply here.
