3-Picoline is a useful precursor to agrochemicals, such as chlorpyrifos. [1] Chlorpyrifos is produced from 3,5,6-trichloro-2-pyridinol, which is generated from 3-picoline by way of cyanopyridine. This conversion involves the ammoxidation of 3-methylpyridine: CH 3 C 5 H 4 N + 1.5 O 2 + NH 3 → NCC 5 H 4 N + 3 H 2 O. 3-Cyanopyridine is also a ...
These recommendations take into account considerations for the efficacy and duration of immunity (DOI) [1] of available vaccines; environmental risks and likelihood of exposure; the specific needs and risks associated with age and overall health status of different cats and cat populations; and socioeconomic limitations.

By 1879, the Austrian chemist Hugo Weidel had succeeded in isolating and characterizing three isomers of picoline, which he denoted α–, β–, and γ–picoline: [10] α–picoline was the main component of impure picoline; it was accompanied by small quantities of β–picoline; and γ–picoline was produced by Baeyer's dry distillation of ...
Vaccines are not injected intravenously into the bloodstream. Most injections deposit a small dose into a muscle, but some are given superficially just under the skin surface or deeper beneath the skin. [1] Fluenz Tetra, a live flu vaccine for children, is administered nasally with 0.1ml of liquid sprayed into each nostril.
In cats, vaccine-associated sarcoma (VAS) occurs at a rate of 1–10 per 10,000 injections. In 1993, a causal relationship between VAS and administration of aluminium adjuvated rabies and FeLV vaccines was established through epidemiologic methods, and in 1996 the Vaccine-Associated Feline Sarcoma Task Force was formed to address the problem.

Picolinic acid is an organic compound with the formula NC 5 H 4 CO 2 H.It is a derivative of pyridine with a carboxylic acid (COOH) substituent at the 2-position. It is an isomer of nicotinic acid and isonicotinic acid, which have the carboxyl side chain at the 3- and 4-positions, respectively.
[3] [4] Vaccines are categorised into conventional and next generation vaccines. [5] [6] Animal vaccines have been found to be the most cost effective and sustainable methods of controlling infectious veterinary diseases. [6] In 2017, the veterinary vaccine industry was valued at US$7 billion and it is predicted to reach US$9 billion in 2024. [7]
A vaccine-associated sarcoma (VAS) or feline injection-site sarcoma (FISS) is a type of malignant tumor found in cats (and, often, dogs and ferrets) which has been linked to certain vaccines. VAS has become a concern for veterinarians and cat owners alike and has resulted in changes in recommended vaccine protocols.
