Methyl 6-quinoxalinecarboxylate

CAS 23088-23-5C10H8N2O2Heterocyclic Building Blocks

Methyl 6-quinoxalinecarboxylate (CAS 23088-23-5) is a nitrogen-containing heterocyclic building block, the methyl ester of quinoxaline-6-carboxylic acid. Its molecular formula is C10H8N2O2 with a molar mass of 188.18 g/mol, and it is a crystalline solid melting at about 97-101 °C. Supplied at 97% assay, it serves chiefly as an intermediate in chemical synthesis and medicinal-chemistry research, where the quinoxaline scaffold and reactive ester support onward functionalisation. Tech Serve Solutions supplies it to research and manufacturing laboratories worldwide.

01 /Applications

Heterocyclic building block

Used as a quinoxaline scaffold in chemical synthesis, providing a fused bicyclic core for the construction of more complex nitrogen heterocycles.

Pharmaceutical intermediate

Serves as an intermediate in medicinal-chemistry and discovery programmes, where the quinoxaline ring is a recognised motif for assembling candidate molecules.

Ester functionalisation

The methyl carboxylate offers a convenient handle for hydrolysis, amidation, reduction or transesterification, enabling further derivatisation of the quinoxaline framework.

Laboratory reagent for research

Employed in academic and industrial laboratories for method development and structure-activity studies built around the quinoxaline-6-carboxylate unit.

06 /Frequently asked questions

What is Methyl 6-quinoxalinecarboxylate used for?

+

It is used principally as a heterocyclic building block and intermediate in chemical synthesis. The quinoxaline scaffold and the reactive methyl ester make it useful in medicinal-chemistry research and for preparing more elaborate nitrogen heterocycles. Tech Serve Solutions supplies it for research and manufacturing use, not for clinical or consumer application.

What is the CAS number and molecular formula of Methyl 6-quinoxalinecarboxylate?

+

The CAS number is 23088-23-5 and the molecular formula is C10H8N2O2, corresponding to a molecular weight of 188.18 g/mol. It is also known as methyl quinoxaline-6-carboxylate or 6-quinoxalinecarboxylic acid methyl ester.

What grade and purity does Tech Serve Solutions supply?

+

Tech Serve Solutions supplies Methyl 6-quinoxalinecarboxylate at a typical assay of 97% as a research and synthesis-grade material. It is a crystalline solid melting at approximately 97-101 °C. We do not represent it as USP, BP or EP pharmacopoeia grade. A certificate of analysis can be provided with each batch on request.

What are the safety and handling precautions for Methyl 6-quinoxalinecarboxylate?

+

It carries GHS07 with the signal word Warning. The hazard statements are H315 (causes skin irritation) and H335 (may cause respiratory irritation); avoid breathing dust (P261). Handle with eye protection, gloves and an N95-type dust mask in a well-ventilated area. It is classified WGK 3 (highly hazardous to water in Germany), so prevent release to drains and the environment. Always consult the Safety Data Sheet before use.

How is Methyl 6-quinoxalinecarboxylate packed, shipped and exported?
