Introduction：Basic information about CAS 4233-33-4|4-Phenyl-1,2,4-triazole-3,5-dione, including its chemical name, molecular formula, synonyms, physicochemical properties, and safety information, etc.
Development and optimization of an LC-MS/MS-based method for simultaneous quantification of vitamin D2 , vitamin D3 , 25-hydroxyvitamin D2 and 25-hydroxyvitamin D3.
J. Sep. Sci. 34(1) , 11-20, (2011)
Simultaneous and accurate measurement of vitamin D and 25-hydroxyvitamin D in biological samples is a barrier limiting our ability to define "optimal" vitamin D status. Thus, our goal was to optimize ...
Examination of structurally selective derivatization of vitamin D(3) analogues by electrospray mass spectrometry.
J. Mass Spectrom. 36(1) , 71-8, (2001)
The structural specificity of vitamin D derivatization by PTAD (4-phenyl-1,2,4-triazoline-3,5-dione) was probed using synthetic analogues and ion trap mass spectrometry. EB 1089, a vitamin D(3) analog...
