Real-World Case Studies
Case Study 1: Textile Dye Manufacturer in India
Challenge: Needed eco-friendly dye with ≥4/5 washfastness for export-grade cotton.
Solution: Formulated AZO dye using 5-amino-o-cresol (0.8% w/w) as coupling agent.
Result: Achieved 4.5/5 fastness rating, reduced wastewater BOD by 18%.
Case Study 2: German Pharmaceutical Company
Challenge: Required cost-effective intermediate for hypertension API batch production.
Solution: Implemented 5-amino-o-cresol in 3-step synthesis (yield: 82%).
Result: Reduced production cost by $12.7/kg compared to previous route.
