Stability: |
Solutions are stable at pH 4-9 (most stable at pH 7);
Below pH 4 tylosin B (desmycosin) is formed as a result of acid hydrolysis;
In neutral and alkaline pH – tylosin aldol (TAD) is formed together with polar degradation products of unknown identity;
When tylosin solution is exposed to daylight, a photodegradation product - isotylosin A (isoTA) is formed. |
