SECTION 10: Stability and reactivity
Reactivity
Sensitive to moisture. Water insoluble.
Chemical stability
Mesalamine is unstable in the presence of water and light, since oxidation and, to a lesser extent, light-catalyzed degradation of the drug occur.

Toxicity
- Toxicity to fish: LC50 - 155 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: LC50 - Daphnia sp. - 12 mg/L - 48 h.
- Toxicity to algae: EC50 - 66 mg/L - 96 h.
- Toxicity to microorganisms: IGC50 - Tetrahymena pyriformis - 64.34 mg/L - 48 h.
Persistence and degradability
ANAEROBIC: Mesalamine, present at 250 mg/L, produced 95.6% methane following a lag phase of 65 days using 2-nitrophenol-adapted sludge in batch assays conducted in 120 ml glass serum flasks and is considered completely biodegradable under anaerobic conditions(1). Mesalamine was completely degraded by a mesophilic sludge in 30 days (mesophilic granular sludge from a full-scale UASB reactor treating chemical industry wastewater of Shell Nederland Chemie at Moerdijk, The Netherlands, VSS concn - 25.5 g/L; specific aceticlastic activity - 0.3 COD/L/g VSS, 30 deg C) following a 20-day lag period(2). It was also completely degraded using a mesophilic floccular sludge from a lab-scale UASB reactor treating cattle manure wastewater - VSS concn 20.5 g/L; specific aceticlastic activity - 0.05 to 0.06 g COD/L/g VSS, so deg C; however, specific incubation and acclimation details were not provided(2). Degradation using a thermophilic sludge was 100% in 48 days following a 34 day lag period - full-scale CSTR reactor digesting primary and secondary sludges at Kur'yanovskaya municipal aeration station, Moscow, Russia - VSS concn 20.5 g/L; specific aceticlastic activity 0.1 g COD/L g VSS, 55 deg C(2).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for mesalamine(SRC), using an estimated log Kow of 0.98(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of mesalamine can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that mesalamine is expected to have very high mobility in soil. A predicted Kd value of 1.37 calculated for sludge samples in the UK, suggests that adsorption to sludge is low(3). Estimated pKa values of 2.09, 5.26 and 13.64(4) indicate that this compound will dissociate to the zwitterion form in the environment(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
