Hello, 

TIFR because in tifr there is world class facilities to do research .
In TIFR many students who are pursuing their post doc from MIT or Stanford told the Labs in TIFR are comparable to their foreign labs.
And faculty also familiar to the students.

Hope this helps 

Hello Pratiksha..

Thanks for contacting Careers360..

TIFR is good for integrated MSc-PhD in chemistry but the thing I cannot say that it is as good as an IIT or IISc .Every college has its own standard but its infrastructure cannot cross IITs 

All the best:)
