Find content-type of sharepoint file

I need to find out the mime-type from the object of type Microsoft.SharePoint.Client.File. For example - if it's a pdf, I need a field which would contain "application/pdf".

I guess you are looking for a MIME type, in SharePoint CSOM API the closest property you could get is file type: 

var file = ctx.Web.GetFileByServerRelativeUrl(fileUrl);
ctx.Load(file, f => f.ListItemAllFields);
ctx.ExecuteQuery();
var fileType = file.ListItemAllFields["File_x0020_Type"];

To get MIME type, System.Web.MimeMapping.GetMimeMapping method could be utilized from .NET (4.5 or above):

var file = ctx.Web.GetFileByServerRelativeUrl(fileUrl);
ctx.Load(file);
ctx.ExecuteQuery();
string mimeType = MimeMapping.GetMimeMapping(file.Name);
