📌 Subject Overview

BP106T Introduction to Pharmaceutical Inorganic and Analytical Chemistry provides essential foundational chemical knowledge for pharmacy students. It covers sources of impurities, official IP limit tests (chloride, sulfate, iron, heavy metals, arsenic), classical analytical methods (acid-base, non-aqueous, precipitation, complexometric, redox titrations), and pharmaceutical inorganic agents (gastrointestinal agents, topical agents, electrolytes, dental products, and radiopharmaceuticals).

BP106T में लिमिट टेस्ट (Limit Tests for Chloride, Sulfate, Arsenic, Iron), टाइट्रेशन (Acid-Base, Redox, Complexometry), और एंटासिड, इलेक्ट्रोलाइट्स व रेडियोफार्मास्यूटिकल्स का अध्ययन किया जाता है।

Prescribed under the new PCI 2026 syllabus, BP106T merges foundational inorganic pharmaceutical compendia with quantitative analytical principles.
