N,N-Dimethyl-3-nitropyridin-2-amine
N,N-Dimethyl-3-nitropyridin-2-amine (CAS 5028-23-9) is a substituted nitropyridine with the molecular formula C7H9N3O2 and a molar mass of 167.17 g/mol. It is a heterocyclic building block in which a pyridine ring carries a dimethylamino group at the 2-position and a nitro group at the adjacent 3-position. Tech Serve Solutions supplies it as a research-grade intermediate for chemical synthesis, where the nitro and aminopyridine functions provide convenient handles for further elaboration.

Heterocyclic building block
Used as a pyridine-based building block in organic and medicinal chemistry research. The combination of a 2-dimethylamino group and a 3-nitro substituent supports the construction of more complex nitrogen heterocycles.
Synthetic intermediate
Serves as an intermediate in multi-step synthesis, where the aromatic nitro group can be carried forward or transformed in subsequent steps to reach target molecules.
Reduction to a diaminopyridine scaffold
The aromatic nitro group is a common precursor to the corresponding amine, allowing reduction to an aminopyridine motif that is widely valued in heterocyclic chemistry. Specific routes should be developed and validated by the user.
Laboratory research and method development
Suitable as a defined reference compound for exploratory chemistry, reaction screening and analytical method development at laboratory scale.

What is N,N-Dimethyl-3-nitropyridin-2-amine used for?
+
It is used mainly as a heterocyclic building block and synthetic intermediate in chemical and pharmaceutical research. The dimethylamino and nitro groups on the pyridine ring make it a convenient starting point for preparing more elaborate nitrogen-containing heterocycles. We supply it for research and manufacturing use, not for consumer or therapeutic applications.
What is the CAS number and molecular formula of N,N-Dimethyl-3-nitropyridin-2-amine?
+
The CAS number is 5028-23-9 and the molecular formula is C7H9N3O2, corresponding to a molecular weight of 167.17 g/mol. It is also described as a 2-(dimethylamino)-3-nitropyridine, reflecting the substituent positions on the pyridine ring.
What grade and purity does Tech Serve Solutions supply?
+
We supply N,N-Dimethyl-3-nitropyridin-2-amine as a research- and technical-grade building block, with a certificate of analysis available for each batch. We do not represent it as a USP, BP or EP pharmacopoeial grade. If you require a specific assay, please state your target purity when requesting a quotation so we can confirm against current stock.
How should N,N-Dimethyl-3-nitropyridin-2-amine be handled and stored?
+
Handle it as a laboratory research chemical, using appropriate gloves, eye protection and adequate ventilation, and avoid generating dust. As an aromatic nitro compound it should be kept away from heat, ignition sources and strong reducing agents, and stored cool, dry and tightly closed. Always review the current Safety Data Sheet before use, as the supplied dataset does not include full GHS classification.
How is N,N-Dimethyl-3-nitropyridin-2-amine packed, shipped and exported?
+
It is packed in clearly labelled, sealed containers sized to the requested quantity, from gram-scale research amounts to larger laboratory packs. Each shipment is accompanied by the relevant documentation and Safety Data Sheet, and is dispatched to global destinations in line with applicable transport and export requirements.
How do I request a sample or quotation?
+
Contact Tech Serve Solutions with the product name, CAS number 5028-23-9 and your required quantity and grade. We will confirm availability, lead time and packing, and arrange a sample or formal quotation for your laboratory or manufacturing project.
