4-PHENYL-1,2,4-TRIAZOLINE-3,5-DIONE Chemical Properties,Uses,Production

Chemical Properties

4-PHENYL-1,2,4-TRIAZOLINE-3,5-DIONE is Red Solid

Uses

4-PHENYL-1,2,4-TRIAZOLINE-3,5-DIONE is used in the methods for determining levels of 1,25 dihydroxyvitamin d2 and d3 in biological and food samples and dietary supplements.

General Description

4-Phenyl-1,2,4-triazoline-3,5-dione, also known as Cookson reagent, is a strong dienophile, which gives a stable Diels-Alder adduct quantitatively within a short time and under mild conditions. It is commonly used as a protecting group of the diene moiety for the synthesis of vitamin D₃ (VD₃)-related compounds.

Purification Methods

PTAD forms carmine red needles by sublimation (ice cold finger) at 100o/0.1mm, and/or by recrystallisation from EtOH. IR: 1760 and 1780 cm-1 . [Cookson et al. Org Synth 51 121 1971, Moore max et al. J Org Chem 39 3700 1974, Beilstein 26 I 57, 26 III/IV 540.]
