How to check for a product card in Bitrix?

Question

1C-Bitrix

I need to embed microdata into a Bitrix template. To do this, you need to edit the product card template. But the parent product card tag is in the general /catalo/index.php catalog template. Therefore, I need to write a condition, if we are in the card, then we use one micro-markup for the block, and if, for example, in the list of goods, then another. Accordingly, I need to somehow check the page for the product card. Tell me how?
