Understanding Sodium Nitroprusside as an API

Chemical Profile and Usage:
Sodium nitroprusside (Na₂[Fe(CN)₅NO]·2H₂O) is a cyanide-containing compound and a nitric oxide donor, inducing rapid vasodilation. Its stability and handling are critical considerations in procurement, requiring suppliers to adhere to stringent quality standards.
Manufacturing Challenges:
Manufacturing sodium nitroprusside involves complex chemistry and strict control over cyanide content, necessitating specialized facilities compliant with Good Manufacturing Practices (GMP). Ensuring stability during storage and transportation is also a key factor influencing supplier selection.
