1-(3-Cyanopropyl)pyridinium chloride
1-(3-Cyanopropyl)pyridinium chloride (CAS 820972-34-7) is a pyridinium-based salt with the molecular formula C9H11ClN2 and a molar mass of 182.65 g/mol. Supplied as a crystalline solid melting at about 130-135 °C, it pairs a pyridinium cation bearing a cyanopropyl chain with a chloride counter-ion. It is used principally as a specialty building block in organic and chemical synthesis and as a precursor in pyridinium ionic-liquid chemistry. Tech Serve Solutions supplies it at an assay of at least 98.5% (T).

Specialty organic synthesis
Serves as an intermediate and reactive building block in fine-chemical and specialty synthesis, where the pyridinium cation and pendant nitrile group provide convenient sites for further functionalisation.
Pyridinium ionic-liquid chemistry
Belongs to the pyridinium class associated with ionic liquids, where the chloride salt can act as a starting material for the preparation of related functionalised ionic-liquid systems.
Quaternary pyridinium precursor
The N-alkylated pyridinium structure makes it a useful precursor for chemistry exploring quaternary pyridinium salts and their derivatives.
Research and laboratory reagent
Used as a research-grade reagent for method development and exploratory studies in academic and industrial laboratories.

What is 1-(3-Cyanopropyl)pyridinium chloride used for?
+
It is used mainly as a specialty building block in organic and chemical synthesis and as a precursor within pyridinium ionic-liquid chemistry. The pyridinium cation and the nitrile-bearing cyanopropyl chain offer practical handles for further functionalisation. For uses beyond these general applications, customers should validate suitability for their own process.
What is the CAS number and molecular formula of 1-(3-Cyanopropyl)pyridinium chloride?
+
Its CAS number is 820972-34-7 and its molecular formula is C9H11ClN2 (Hill notation), giving a molecular weight of 182.65 g/mol. The MDL number is MFCD09265187. It is a crystalline solid with a melting point of approximately 130-135 °C.
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies 1-(3-Cyanopropyl)pyridinium chloride at an assay of at least 98.5% (by titration), with water content not exceeding 0.5%. It is offered as a technical/research-grade material; we do not represent it as USP, BP or EP pharmacopoeial grade. A certificate of analysis is provided with each batch.
What are the safety and handling requirements?
+
The product is classified under GHS with signal word Danger and pictograms GHS05 and GHS07. The hazard statements are H302 (harmful if swallowed), H315 (causes skin irritation), H318 (causes serious eye damage) and H332 (harmful if inhaled). Handle with gloves, eye protection and a suitable N95-type dust mask, avoid dust formation, and consult the Safety Data Sheet before use. Note: WGK 3 (highly hazardous to water).
How is 1-(3-Cyanopropyl)pyridinium chloride packed, shipped and exported?
+
