Quality & Handling
Practical notes
- L-(+) tartaric acid (CAS 87-69-4) is the common food/pharma isomer; DL- is available for industrial uses.
- Keep dry and sealed; tartrate salts may cake if exposed to humidity. Break up gently before use.
- For leavening, match acid value and reaction rate to bicarbonate choice; consult our application support.
