Yes Michael

.... and also the other dioxane analytical standards

1,4 dioxane - d8 as internal standard and the 1,4 dioxane reagent grade

No NMR facility here

it's very far from here

for method other than NMR

do u have a suggestion ?

Analytical standards are usually expensive. If you just want a non-analytical quuality sample, for identification purposes, whose purity is of no concern, I would advise to contact any chemicals provider there at Philippines, just like those:

One of them surely can help you!
