Overview
Furosemide (CAS 54-31-9 ), also known commercially as Lasix, is an active pharmaceutical ingredient (API) in the loop diuretic class. It is used in the manufacture of finished dosage forms targeting fluid retention and edema-related conditions.
This material is utilized across human and veterinary pharmaceutical markets. Furosemide is the primary API in oral tablet formulations, where it is manufactured at standardized strengths for prescription drug products.
Injectable solution manufacturing represents a distinct supply channel, requiring high-purity pharmaceutical-grade material compatible with parenteral processing standards. This ensures safety and efficacy in clinical settings.
Veterinary pharmaceutical producers source this ingredient for companion animal and livestock formulations. It is particularly effective for cardiac and renal indications within the animal health sector.
The compound also serves as a reference standard and analytical reagent in QC laboratories. These facilities use it for validating diuretic drug products and ensuring consistent manufacturing quality.
The product is supplied as a white to off-white crystalline powder. Pharmaceutical-grade material is available to USP , BP , and Ph. Eur. specifications, which are the primary standards required.
Bulk API is typically offered in kilogram and multi-kilogram quantities to meet industrial demand. Documentation packages include CoA, DMF references, and GMP certification to support regulatory submissions.
