Which of the following statements about fine chemical is correct? It

Analyze the question: The question asks which statement correctly describes a fine chemical.

Concept: In industrial chemistry, chemicals are grouped as:

• Heavy (bulk) chemicals: produced in very large quantities, usually at lower cost and often lower purity. Examples: sulphuric acid, sodium hydroxide, ammonia, sodium carbonate.
• Fine chemicals: produced in small quantities, with high purity and at high cost. They are used for specialised purposes such as pharmaceuticals, reagents, dyes, and perfumes or flavourings. Examples: drugs, vitamins, laboratory-grade reagents.

Evaluate each option:

• A. Is injurious to health: Not a defining feature. Many fine chemicals, such as medicines and vitamins, are beneficial. ✗
• B. Has low degree of purity: Wrong. Fine chemicals have a high degree of purity. ✗
• C. Is produced in relatively small amount: Correct. Fine chemicals are made in limited quantities compared with heavy chemicals. ✓
• D. Can be stored for a long time: Not a defining property. Storage life depends on the particular chemical, and some fine chemicals are unstable. ✗

Exam tip: Remember it as "Fine = Few, Fussy-pure, Fancy-priced": small quantity, high purity, high price. Heavy chemicals are the opposite: large quantity, lower purity and lower price.
