Introduction
3-Chloropyridine, with the CAS number 626-60-8 (not 98-98-6), is a pivotal heterocyclic compound in organic synthesis. Its molecular formula is C₅H₄ClN, and it serves as a key intermediate in pharmaceuticals, pesticides, and agrochemicals. This colorless to pale yellow liquid is utilized in the production of agrochemicals like pyridine-based herbicides and pharmaceuticals such as antivirals and anticancer agents. Its reactivity stems from the chlorine atom at the 3-position, enabling nucleophilic substitution and cross-coupling reactions. However, it poses health risks (GHS Category 3) due to potential toxicity via inhalation or skin contact, necessitating proper handling and storage under inert conditions to prevent decomposition.
Usage： 3-Chloropyridine Used as pharmaceutical intermediates.
Packaging and Shipping： 25kgs/Bag or Drum or as required by buyer.
Storage: Store in a cool, ventilated place, protect from sun, heat and moisture.Storage and transportation according to general chemical regulations.
