Heterocyclic building block
Serves as a halogenated pyridine scaffold for constructing more complex nitrogen heterocycles. The assembled chloride, alkyne and protected-amine functions allow sequential, selective elaboration during multi-step synthesis.
Cross-coupling intermediate
The 2-chloro substituent on the pyridine ring provides a handle for transition-metal-catalysed cross-coupling reactions such as Suzuki, Negishi and Buchwald-Hartwig amination, enabling further carbon-carbon and carbon-nitrogen bond formation.
Terminal alkyne precursor
The trimethylsilyl (TMS) group protects the ethynyl function and can be removed under mild basic or fluoride conditions to reveal a terminal alkyne, which is widely used in Sonogashira coupling and click (CuAAC) chemistry.
Protected aminopyridine reagent
The pivalamide masks the 3-amino group as a robust, sterically hindered amide that tolerates many reaction conditions and directs metalation, then can be hydrolysed to regenerate the free amine when required.
Pharmaceutical and agrochemical research
As an organosilicon-functionalised pyridine, it is suited to discovery and route-development programmes that prepare pyridine-containing candidate molecules. Specific end-use should be confirmed by the customer for their application.

+
Its CAS number is 1142191-97-6 and its molecular formula is C15H21ClN2OSi, corresponding to a molecular weight of 308.88 g/mol.
What grade and purity does Tech Serve Solutions supply?
+
We supply this compound as a research- and laboratory-grade reagent intended for synthesis. The verified data does not specify a fixed assay, so a current specification and certificate of analysis are provided with each batch on request. We do not represent it as a USP, BP or EP pharmacopoeial grade.
What safety and handling precautions apply?
+
No GHS classification is included in the verified data supplied to us, so a formal hazard profile is not confirmed here. As with any research chemical of incomplete hazard data, handle it as potentially hazardous: work in a fume hood, wear gloves, eye protection and a lab coat, avoid dust, skin and eye contact, and keep it dry and sealed. Always consult our current Safety Data Sheet before use.
How is N-(2-Chloro-6-((trimethylsilyl)ethynyl)pyridin-3-yl)pivalamide packed, shipped and exported?
+
It is packed in suitably sealed containers sized to the order, from gram quantities to larger research lots, with appropriate inner protection and labelling. As a specialist exporter since 1998, Tech Serve Solutions arranges compliant international documentation and shipping to laboratories and manufacturers worldwide.
How do I request a sample or quote?
+
Contact Tech Serve Solutions with your required quantity, packaging and destination, quoting CAS 1142191-97-6. We will respond with availability, lead time, specification details and a formal quotation, and can arrange a sample where appropriate.
