Prudence Lifecare Pvt. Ltd.
3-(7-Cyano-5-(2-Aminopropyl)Indolin-1-yl)Propyl Benzoate
Manufactured and supplied from our WHO-GMP, GLP and ISO 9001:2015 certified facility in Ankleshwar, Gujarat, India. Available as the racemic aminopropyl- indoline (CAS 1338365-54-0) and its (S)-enantiomer (CAS 1201180-97-3) — both related to the chiral resolution step used to manufacture the (R)-isomer that goes into Silodosin.

What is this intermediate?
3-(7-Cyano-5-(2-Aminopropyl)Indolin-1-yl)Propyl Benzoate is the aminopropyl-indoline building block used industry-wide in Silodosin synthesis. Only the (R)-configured enantiomer (CAS 239463-72-0 — see our separate page for that grade) carries forward into the finished Silodosin API; this racemic starting material (CAS 1338365-54-0) and the (S)-enantiomer (CAS 1201180-97-3) recovered during chiral resolution are related forms in the same synthesis route. Prudence Lifecare's material is manufactured under the same quality systems that govern our full API and intermediates portfolio.
Application
- Silodosin synthesis — racemic starting material
- Chiral resolution intermediate
- Custom synthesis & CDMO supply
- Pharmaceutical research & QC reference
