CAS number: 288-94-8
1H-tetrazole is a tetrazole tautomer where the proton is located on the 1st position. It is a tetrazole and a one-carbon compound. It is a tautomer of a 2H-tetrazole and a 5H-tetrazole.
IR difference spectrum after 1 min photolysis (254 nm) of 5-phenyltetrazole 2 in Ar matrix at 12 K. Positive peaks: photolysis products, largely benzonitrile imine 6; the peak near 1700 cm−1 is due to an impurity on the deposition window. Negative peaks: reacted tetrazole 2.
CAS number: 288-99-3

Chlorpyrifos is an insecticide that is a white crystal-like solid with a strong odor. It does not mix well with water, so it is usually mixed with oily liquids before it is applied to crops or animals. It may also be applied to crops in a capsule form. Chlorpyrifos has been widely used in homes and on farms. In the home, it is used to control cockroaches, fleas, and termites; it is also used in some pet flea and tick collars. On the farm, it is used to control ticks on cattle and as a spray to control crop pests.
Selected haloarenes: Pestalachloride D, 2,4,6-Tribromo-m-cresol, Eosine Y, Liothyronine, Chlorpyrifos, mC21-A.
