Feb 9 2017 5:17PM	High	Acknowledged	How can we access the smiles giving a CAS number. The Smiles is not any more displayed when we make a search You can find the SMILES on a ChemSpider record by clicking on "More details". You can also change the view on the Search Results page by clicking the rightmost box with three horizontal lines, which is directly below "Create data slice".

Apr 24 2015 11:37AM	Normal	Acknowledged	Boiling point data are confusing - formaldehyde is a gas at room temperature, its b.p. cannot be 96 C. Probably it refers to an aqueous solution. Thank you for your feedback - where we can we intentionally provide a link back to the original source of the data - so in this case it is possible to easily see why this unusual value is displayed. I was able to follow these links and see that the b.p. is for a solution in methanol - i will now remove these incorrect values.

Dec 3 2009 6:48PM	Normal	Fixed	The wiki description says that "Formaldehyde also exist as cyclic trimer (trioxane) and the polymer (paraformaldehyde)." This statement is an error since the term “also exist” generally implies a simple change of state or polymorphic form of the same chemical entity. While formaldehyde is a reactant used in the formation of trioxane or paraformaldehyde, these latter are reaction products that are now distinct chemical entities. This seems an easy error to correct, but when it comes to aqueous solution with formaldehyde "formalin", I wonder what tack I should take? Formaldehyde is a gas at room temperature but it is rarely handled in that form. Instead, it is instead most commonly encountered as a solution of water and formaldehyde called formalin (note, also contains a small amount of methanol to inhibit polymerization reactions). From a ChemSpider perspective, should I take a hard line and stick to the chemical structure or take a more inclusive approach? Any errors in the WIkipedia statements should be redirected to the page on Wikipedia for discussion. The ChemSPider record is a page about the "structure" as it were but there is always a need for flexibility as it is not possible to "draw" a formaldehyde solution. I recommend inclusivity and common sense.
