Meaning and Definition
A salt or derivative formed when a mercaptan (a thiol) reacts with a base, resulting in the replacement of the hydrogen atom of the thiol group with a metal or other cation.
In organic chemistry and biochemistry, mercaptides are important intermediates or reagents, often involved in reactions where the sulfur atom acts as a nucleophile or a ligand in coordination chemistry.

Common Mistakes When Using “mercaptide”
- Pronouncing it as /ˈmɜː.kəp.taɪd/ (with stress on the first syllable). Correct stress is on the second syllable.
- Using it as a synonym for any sulfur-containing compound.
- Misspelling as 'mercaptid' or 'mercaptaide'.
FAQ
Frequently Asked Questions
No, it is a highly specialised term used only in chemistry.
Yes, in modern chemical nomenclature, 'thiolate' is the preferred IUPAC term, but 'mercaptide' is still widely used, especially in older literature and specific contexts.
The main difference is in the vowel of the first syllable: British /ɜː/ (as in 'her') vs. American /ɚ/ (the r-colored schwa). The stress pattern (/ˌmɜːˈkæp.taɪd/) is the same.
A general language learner would not. It is only relevant for students or professionals in chemistry, biochemistry, or related scientific fields who need to read technical literature in English.

Learning
Memory Aids
Mnemonic
Think: 'MERCAPTan' loses its 'H' (hydrogen) to become 'MERCAPTide' – the 'ide' ending often indicates a negative ion or salt in chemistry (like chloride, oxide).
Conceptual Metaphor
A mercaptide is to a mercaptan as a salt (e.g., sodium chloride) is to an acid (hydrochloric acid).
