Authentic Aldehyde Standards for NMR

Check if the same lab product or an alternative is used in the 5 most similar protocols
Authentic aldehydes employed for 1H NMR reference purposes, including n-hexanal, n-octanal, trans-2-octenal, trans-2-nonenal trans,trans-deca-2,4-dienal, etc. were obtained from the Sigma-Aldrich Chemical Co. (UK). Crotonaldehyde (butenal) was also purchased from Sigma-Aldrich as a 20:1 molar ratio of its trans-(E-):cis-(Z-) isomers in order to permit assignments of resonances for cis-2-alkenal LOPs in thermally-stressed culinary oils.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
