nitrogen mustard
Low/Very SpecializedTechnical/Scientific
Definition
Meaning
A class of chemical compounds related to mustard gas, used as chemotherapeutic agents to treat cancer by damaging DNA.
Any of a family of cytotoxic alkylating agents derived from bis(2-chloroethyl)amine, used primarily in chemotherapy and historically developed from chemical warfare research.
Linguistics
Semantic Notes
The term combines 'nitrogen' (referring to the core amine group) with 'mustard' (due to structural and historical relation to sulfur mustard gas). It denotes both a specific compound and a class of related agents (e.g., mechlorethamine, cyclophosphamide).
Dialectal Variation

Learning
Memory Aids
Mnemonic
Think: 'NITROGEN' for the 'N' in the chemical structure + 'MUSTARD' like the poisonous gas it's related to. Together, they form a 'mustard' that fights cancer (not for sandwiches!).
Conceptual Metaphor
A CONTROLLED POISON / A DOUBLE-EDGED SWORD. The metaphor highlights its origin as a destructive chemical weapon repurposed into a life-saving (though toxic) medicine.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'азотная горчица' – this is incorrect and nonsensical. The correct established term is 'азотистый иприт' or more commonly, specific drug names like 'мехлорэтамин'.
- Do not confuse with the condiment 'mustard' ('горчица'). The connection is purely historical/chemical, not culinary.
Common Mistakes
- Mispronouncing 'mustard' as /ˈmjuː.stɑːd/ or /ˈmuː.stɑːd/.
- Using it as a general term for all chemotherapy drugs (it's a specific class).
- Incorrectly associating it with food allergies.
- Spelling as 'nitrogen musterd' or 'nitrojen mustard'.

FAQ
Frequently Asked Questions
No, they are completely unrelated. 'Nitrogen mustard' is a toxic chemical compound used in medicine and historically in warfare. The name comes from its structural similarity to sulfur mustard gas, not from the food condiment.
It is used almost exclusively as a chemotherapeutic drug (alkylating agent) to treat certain types of cancer, such as Hodgkin's lymphoma and some leukaemias. Specific drugs include mechlorethamine and cyclophosphamide.
The name comes from its historical and chemical relationship to 'sulfur mustard gas' (yperite), a blistering agent used in WWI. Some nitrogen mustards have a similar smell and vesicant (blistering) property, though their primary medical use is for their cell-damaging (cytotoxic) effects.
Yes, it is a potent cytotoxic and mutagenic agent. In a controlled medical setting, it is administered in precise doses to target cancer cells, but it has significant side effects. Outside such controls, exposure is highly dangerous.
