Yes. The standard allows for bromophenol blue indicator, but this is less accurate for colored or dark samples. The potentiometric (pH meter) method is preferred.
: Basicity attributed specifically to primary amines.
: Standardized 0.1 N Hydrochloric acid (HCl) in isopropyl alcohol.
That’s where comes in. Known formally as the Standard Test Methods for Total, Primary, Secondary, and Tertiary Amine Values of Fatty Amines by Alternative Indicator Method , this standard provides a critical chemical "fingerprint" for these vital compounds. What Exactly is ASTM D2074?
