Acetylsalicylic acid
aspirin
low dose aspirin is use as a “blood thinner” to prevent blood clots.
aspirin
substitute for aspirin
Acetaminophen
used in suntan lotions to prevent the dangerous uv rays from reaching the skin
p-aminobenzoic acid
Antipyretic and analgesic but has lately been supplanted by phenacetin which is less toxic
Acetanilide
amide of niacin
Niacinamide
-prevents pellagra
Nicotinamide
discovered in 1936 to have a definite therapeutic effect against such diseases as pneumonia, diarrhea and streptococcal infections.
Sulphanilamide
cause nausea, dizziness, anemia and other toxic reactions in the body; has been replaced by the so called sulfa drugs.

SOME IMPORTANT ACID DERIVATIVES
Acetanilide
Niacinamide
Nicotinamide
Sulphalinamide
- react very rapidly with water to form Carboxylic acid and HCl.
Acid chlorides
- Acid chlorides
positive result
turbidity of substance and the warming
effect due to the presence of
HCl
reacts with acetyl chloride producing AgCl which is the white ppt.
AgNO3
- Introducing (blank) produce effervescence due to the production of CO2 in the form of gas.
NaHCO3
- even though it is less reactive than acid chlorides,
- its hydrolysis yields two carboxylic acids, which did not produce any visible result.
Acid anhydride
- hydrolysis occurs very slowly, only becomes rapid with the introduction of acid or base
- Ethyl acetate
