C# escapes double quote " symbol automatically with backslash

I am writing some website parser and analyzer.

And I am building a JSON object from parsed parameters. For example a website has title
Buy best phones from "NOKIA COMPANY LTD" As you can see title has double quote symbol: " So when I parse title, I get this:

Buy best phones from \"NOKIA COMPANY LTD\" and call anyone

Then I generate a JSON object which will be used by frontend developers. I am using JSON newton soft library like this =

 var obj = new 
    { 
      Title = parsedTitle, 
      H1 = "some h1"
    };

JsonConvert.SerializeObject(obj, settings);

And as and out put I get not valid json, so frontend developers get an error.

Output JSON will be something like:

{
  "title": " Buy best phones from \\"
   NOKIA COMPANY LTD\\" and call anyone",
  "h1:: "some h1"
}

As you can see it is not valid JSON. What do I do?
