4. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 is the anthelmintic bitoscanate that has been used against hookworm, and the laboratory grade is supplied for research.

1. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 should be stored in a cool, dry, dark, well-ventilated place under an inert atmosphere, with the container kept tightly closed, because it is moisture sensitive and hydrolyzes in water.
2. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 should be kept away from water and oxidizing agents; supplier guidance ranges from a cool place below 15°C to refrigerated or −20°C storage.
3. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 is stable under the recommended dry storage conditions, and the current laboratory safety data sheet does not state a fixed shelf life, so the label should be followed.

1. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 is toxic if swallowed (H301), causes skin irritation (H315), and causes serious eye irritation (H319).
2. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 may cause allergy or asthma symptoms or breathing difficulties if inhaled (H334) and may cause respiratory irritation (H335).
3. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 is very toxic to aquatic life with long-lasting effects (H410).
4. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 is a combustible solid that melts at about 129–133°C; the laboratory safety data sheet gives no flash point, a database lists about 167°C, and heating can release carbon oxides, sulfur oxides, and nitrogen oxides.

1. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 is not safe for uncontrolled handling because it is toxic if swallowed, can sensitize the respiratory tract, and is very toxic to aquatic life.
2. 1,4-Phenylene diisothiocyanate CAS 4044-65-9 requires protective gloves, safety goggles, and protective clothing in a fume hood, and dust must not be breathed.
