We recently had submitted for analysis some capsules containing a white crystalline powder. A methanolic solution of the powder produced a mass spectrum with base peak of 110, and other prominent ions at 130, 145, 160, 174, 241, and 270 (mass ion). We have found no matches to anything in our MS libraries, nor anything in online databases. UV absorption in aqueous solution produced absorbance maxima at 275 in acid, 289 in base.
Does this MS sound familiar to anyone?
Thanks in advance.
