While ASTM D2074 is highly effective, modern laboratories frequently compare it against alternative standards depending on their available technology: intrigued. "What did you find
The team leaned in, intrigued. "What did you find, Dr. Patel?" Rachel asked.
Acetic anhydride (used to block primary and secondary amines when isolating tertiary values). Bromphenol blue indicator solution.
A separate sample portion is treated with salicylaldehyde. This reaction blocks the primary amines, allowing only the secondary and tertiary amines to be titrated.
