Metabolism / Metabolites
Aromatic aldehydes are almost completely oxidized to their corresponding acids in vivo. For example, in rabbits, p-tolualdehyde is converted to p-toluic acid, which is detected in urine as an ester glucuronide. Resting cells of Pseudomonas aeruginosa can oxidize p-tolualdehyde to p-toluic acid. Perillaldehyde dehydrogenase isolated from Pseudomonas aeruginosa catalyzes the oxidation of m-tolualdehyde and p-tolualdehyde, but not o-tolualdehyde. Aldehydes are readily oxidized to organic acids. Aldehyde oxidation is catalyzed by aldehyde dehydrogenase, an enzyme found in the brain, erythrocytes, liver, kidneys, heart, and placenta. /Aldehydes/ The detoxification of aldehydes occurs primarily through two pathways: (1) oxidation to readily metabolizable acids; (2) inactivation by reaction with sulfhydryl groups (especially glutathione). In cases of decreased glutathione levels or inhibition of aldehyde dehydrogenase (e.g., disulfiram therapy), the acute and chronic effects of aldehyde toxicity may be more fully manifested. /Aldehydes/ For more complete metabolite/metabolite data on 4-methylbenzaldehyde (7 metabolites in total), please visit the HSDB record page. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (20.81 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (20.81 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (20.81 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
