Ethyl chloro[(4-methoxyphenyl)hydrazono]acetate
Ethyl chloro[(4-methoxyphenyl)hydrazono]acetate (CAS: 27143-07-3) is a defined small-molecule organic intermediate supplied as a yellow to dark-yellow solid. Reference and product listings identify it as an intermediate associated with apixaban synthesis and as an apixaban-related impurity or reference material. Its listed applications therefore encompass both synthetic work and research or analytical workflows involving apixaban-related materials. Product listings indicate research-use status and cold storage at 2–8°C. Before use, confirm isomer designation, handling requirements, and suitability against the lot-specific certificate of analysis and safety data sheet.
• Used as a synthetic intermediate in research and process development related to apixaban synthesis.
• Offered as an apixaban-related impurity/reference material for analytical research, including method development and comparison with authenticated reference material.
• Can support pharmaceutical quality-control investigations when the specific identity, isomer designation, and assay are confirmed for the supplied lot.
• Listed in research-use quantities; it is not presented here as an approved active pharmaceutical ingredient or as a food, cosmetic, or consumer-use ingredient.
