隔离

You use it when you want to describe a state of separation. You can use it as a verb like 隔离他 (isolate him). You can also use it as a noun like 进行隔离 (carry out isolation). It often pairs with 自我 (self) to mean self-quarantine. It is a very versatile word for your daily vocabulary.

Use it when discussing health and safety protocols. It is perfect for technical talk like soundproofing a studio. Use it when you are feeling overwhelmed and need a break. If your roommate has a cold, tell them to 隔离. If you are building a house, talk about 隔音 (sound isolation). It is a very practical, everyday word.

Do not use it for a simple breakup with a partner. That is usually 分手. Do not use it if you just missed a bus and feel lonely. 隔离 implies a deliberate act of partitioning. It is a bit too heavy for just 'feeling left out' at a party. Using it there might make you sound like a biohazard!
