Storing and handling 4,4'-Thiodianiline
Storage conditions
PRECAUTIONS FOR "CARCINOGENS": Storage site should be as close as practical to lab in which carcinogens are to be used, so that only small quantities required for ... expt need to be carried. Carcinogens should be kept in only one section of cupboard, an explosion-proof refrigerator or freezer (depending on chemicophysical properties ...) that bears appropriate label. An inventory ... should be kept, showing quantity of carcinogen & date it was acquired ... Facilities for dispensing ... should be contiguous to storage area. /Chemical Carcinogens/

Reactivity
4,4'-THIODIANILINE is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. May generate heat with these materials and hydrogen gas or hydrogen sulfide gas. May liberate hydrogen sulfide if heated to decomposition or mixed with an acid. Also incompatible with peroxides, phenols (acidic), epoxides, anhydrides, and acid halides.

Safety Data Sheet
Getting an SDS for 4,4'-Thiodianiline
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 4,4'-Thiodianiline issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
