Which common reference would you use to find information on chemical attributes of a drug?

The Merck Index is a comprehensive reference that provides detailed information about the properties, uses, and chemical characteristics of drugs and compounds. It is particularly valuable for those looking to understand the chemical attributes of substances, including their chemical structure, pharmacological effects, and any relevant safety or toxicity information. This makes it an ideal choice for accessing in-depth data on various drugs and their attributes.

Other references, while useful for different aspects of drug information, may not focus as much specifically on the chemical properties and attributes. For instance, Drug Facts and Comparison provides concise drug comparisons but tends to emphasize therapeutic categories rather than detailed chemical information. Martindale offers a broader overview of drugs but is more oriented towards clinical uses and international drug information. USP DI focuses mainly on drug information relevant to healthcare professionals and patients, with an emphasis on safety and usage rather than in-depth chemical details. Thus, for someone specifically seeking chemical attributes, The Merck Index stands out as the most authoritative and specialized resource.
