N-butyl-N-nitrosourea

N-butyl-N-nitrosourea (CAS 869-01-2), also referenced in research procurement as N-Nitroso-N-butylurea, is a nitrosourea compound used primarily as a chemical carcinogen in controlled pharmaceutical and biomedical research settings.

It functions as an alkylating agent, enabling researchers to induce targeted DNA damage in experimental models. Its primary application is in preclinical oncology research, where it is used to establish animal tumor models.

These models are essential for evaluating anticancer drug candidates and treatment protocols. Pharmaceutical researchers use it to study carcinogenesis mechanisms, particularly in gastric and bladder cancer models, supporting the development of new therapeutic compounds.

It also serves as a reference compound in genotoxicity and mutagenicity assays, where reproducible DNA alkylation activity is required for comparative studies. Regulatory toxicology programs may source it as a positive control substance.

N-butyl-N-nitrosourea is supplied as a solid, typically in small research-quantity formats reflecting its specialized and controlled-use nature. It is handled under research-grade specifications for laboratory procurement.

The compound is generally available through chemical suppliers serving pharmaceutical R&D channels. Given regulatory considerations around nitrosourea compounds, buyers should confirm supplier compliance with applicable handling requirements.
