Used in synthesizing azo dyes for textiles (e.g., acid dyes, direct dyes) with enhanced lightfastness.

Intermediate in antihypertensive drugs and antiseptic formulations due to phenolic hydroxyl group.

Key component in fungicides and herbicides targeting crop pathogens like Fusarium species.

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%.

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.

Request Form:

Storage: Keep in airtight container at 15-25°C, away from strong oxidizers.

Safety: Use NIOSH-approved respirator when handling powder form (LD50 oral-rat: 1200 mg/kg).
