Study Notes

Inorganic Chemistry Unit 1

  • Pharmaceutical Inorganic Chemistry: This branch of science studies inorganic compounds used in drug/medicine preparation.
  • Examples of Inorganic Compounds Used: Sodium Chloride (NaCl), Hydrochloric Acid (HCl), Sodium Bicarbonate, Copper Sulphate.
  • Pharmacopoeia: A standard official book containing formulas, details, and information on authorized drugs.
  • Pharmacopoeia Origins: Derived from Greek, "pharmakon" = "drug" and "poeia" = "to make".
  • Pharmacopoeia Functions: Contains standards for drugs, dosage forms, and pharmaceutical aids. Published by a country's government.
  • Common Impurities & Limit Tests: Chloride, Sulphate, Iron, Arsenic, Lead, and Heavy metals; limit tests are used for quantifying these.

Indian Pharmacopoeia (I.P.)

  • Official Documents: Responsible for pharmaceutical quality control in India.
  • Drug Standards: Defines identity, purity, safety, and strength of drugs.
  • Approval & Rules: Approved under the Drug and Cosmetic Act 1940 and Rules 1945.
  • Published By: The Indian Pharmacopoeia Commission (IPC), under the Ministry of Health and Family Welfare.
  • I.P. Contains: Monographs with details on various drugs, including sources, tests, formulas, uses, dosage, and storage.
  • Editions & Supplements: Various editions and supplements (addenda) have been published over the years.
  • Historical development: First pharmacopoeia published in 1833

Impurities: Sources & Types

  • Unwanted Substances Foreign substances in pharmaceuticals impacting quality and potentially causing toxicity.
  • Organic Impurities: Derived from drug/substance synthesis/storage, raw materials, by-products, excipients, or reagents. Often hard to identify.
  • Inorganic Impurities: Often produced during manufacturing from reagents, inorganic salts, heavy metals, or catalysts. Often easily identified.
  • Residual Solvents: Impurities present in pharmaceutical products from solvents used in manufacturing.
  • Destructive vs. Constructive Impurities: The former negatively affect substances, while the latter positively influence them.

Limit Tests

  • Quantitative Tests: Designed to detect & quantify small amounts of impurities.
  • Principle: Comparing turbidity (cloudiness) of test solution with a standard solution.
  • Purpose: Identifying and controlling the amount of specific substances present.
  • Specific Examples: Limit tests for chloride, sulphate, arsenic, iron, lead, and heavy metals.

Limit Test for Chloride

  • Principle: Silver nitrate reacts with chloride ions to form insoluble silver chloride - precipitation of turbidity.
  • Procedure: Prepare test soln & standard soln, and compare the amount of turbidity of two solutions by using Nessler cylinder.

Other Limit Tests

  • Limit Test for Sulphate: Reaction with barium chloride, forming barium sulphate precipitate.
  • Limit Test for Arsenic: Utilizing zinc and hydrochloric acid to convert arsenic to arsine gas, reacting with mercuric chloride paper to produce a stain.
  • Limit Test for Iron: Reaction with thioglycolic acid, forming a purple complex(comparison color intensity).
  • Limit Test for Lead: Reaction with diphenylthiocarbazone(dithizone) to form a red-colored lead complex(comparing colors).
  • Limit Test for Heavy Metals: Reaction with hydrogen sulphide to produce a metal sulphide precipitate, compare color intensity.

Important Considerations/Procedures in Limit Test

  • Use appropriate apparatus and chemicals correctly.
  • Carefully compare the intensities of colors.
  • Monitor reaction times (periods)
  • Record Observations accurately and quickly.
  • Properly label and store chemicals and materials-
