1,3,5-Trimethoxybenzene
Based on 1 publication(s) in Google Scholar
1,3,5-Trimethoxybenzene (TRIMETHYL PHLOROGLUCINOL) is an electrophilic substitution reaction substrate targeting free chlorine (Cl+) and free bromine (Br+). 1,3,5-Trimethoxybenzene has highly selective electrophilic addition characteristics. By capturing halogens, it undergoes specific substitution reactions to generate stable halogenated products. 1,3,5-Trimethoxybenzene can not only quench residual oxidants, but also quantify the halogen concentration by detecting the product without affecting the stability of redox-sensitive disinfection byproducts (DBPs). 1,3,5-Trimethoxybenzene is mainly used in water quality testing and quantitative analysis of free chlorine/bromine in water. At the same time, in phytochemistry, it is a key component of rose fragrance and participates in the study of pollination attraction mechanism.

Biological Activity
1,3,5-Trimethoxybenzene (360 μM; 5 min) can react with free chlorine/bromine to generate single halogenated products (Cl-TMB/Br-TMB). 1,3,5-Trimethoxybenzene can quench the residual halogen through a specific substitution reaction and quantitatively detect it[2.
1,3,5-Trimethoxybenzene (252 μM; 6 min) can effectively quench the chlorination reaction, and the quenching effect is not significantly different from that of sodium thiosulfate[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (14.86 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (14.86 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
