What is Nonadecanoic acid?
Nonadecanoic acid (CAS 646-30-0), also known as n-Nonadecylic acid, is a saturated C19 fatty acid used as a functional ingredient and reference standard.
Where is Nonadecanoic acid used?
- Specialty chemicals: emulsification and lubrication where precise carbon chain length matters
- Analytical and food science laboratories: internal standard for fatty acid profiling
- Lubricants: boundary lubrication in metalworking fluids and specialty greases
- Personal care: emulsifier and texture modifier in creams and ointments
- Food-grade applications: processing aid and lipid component in nutritional research formulations
- Its odd-chain structure distinguishes it from naturally abundant even-chain fatty acids during GC analysis.
Commercial specifications
- High-purity grades of 98 to 99 percent for analytical and reference standard applications
- Packaging from small laboratory quantities to bulk industrial quantities
