Not applicable. 1,3-Phenylene tetraphenyl bis(phosphate) is an industrial flame retardant and has no specific biological target for therapeutic purposes. As a flame retardant, it acts by promoting char formation during combustion. In toxicological research, it is studied as an environmental contaminant and may have weak endocrine-disrupting activity. It does not bind to any specific receptor or enzyme for pharmacological benefit. Its utility is as an analytical reference standard.

|---|---|
| ln Vitro |
In vitro, this compound is not used for biological activity or drug discovery. It is a chemical standard for analytical method development. For GC-MS analysis, it is dissolved in hexane (1 mg/mL). Calibration standards are prepared at 0.1-50 ug/mL. It is used to quantify OPFRs in environmental samples (dust, sediment). It may show weak anti-androgenic activity in reporter assays at very high concentrations (100 uM), but this is not a primary application. It does not have direct cell-based activity.
|
| ln Vivo |
In vivo, this compound is not administered for therapeutic purposes. It is used in animal studies as a model compound to investigate the bioaccumulation and metabolism of organophosphate flame retardants. In a 28-day feeding study in rats, administration of 100 mg/kg/day may be performed to examine its effects on the liver or thyroid. These are toxicological studies, not efficacy models.

| Enzyme Assay |
General protocol for in vitro analytical use: Prepare a 1 mg/mL stock solution in n-hexane. Prepare calibration standards in hexane at 0.1, 0.5, 1, 5, 10, 25, 50, 100 ug/mL. Add 10 uL of internal standard (e.g., Triphenyl phosphate-d15, 10 ug/mL) per mL of standard. Inject 1 uL into a GC-MS with a DB-5MS column (30 m × 0.25 mm). Oven program: 80degC for 1 min, ramp 20degC/min to 350degC, hold 10 min. Detect in EI mode with SIM ions m/z 437, 279. For sample preparation, extract dust (100 mg) with 10 mL hexane:acetone (1:1), sonicate, centrifuge, evaporate, and reconstitute in 1 mL hexane. Store the compound at room temperature. For LC-MS, use C18 column with water:acetonitrile (0.1% formic acid), positive mode, m/z 575 [M+H]+.

| Cell Assay |
General protocol for in vitro cell-based experiments: For an androgen receptor antagonism screening assay, culture MDA-kb2 cells in RPMI-1640 with 10% charcoal-stripped FBS. Seed in 96-well plates (1×10^4 cells/well). Treat with the compound (1-100 uM) and 1 nM DHT for 24 h. Measure luciferase activity. The compound may cause weak inhibition at 100 uM. Perform a parallel MTT assay to confirm no cytotoxicity. This is a toxicological hazard assessment, not drug discovery.
|
| Animal Protocol |
General protocol for in vivo animal experiments: For a toxicokinetic study, administer the compound (100 mg/kg, oral) in corn oil to male Sprague-Dawley rats (n=5). Collect blood at 0, 1, 2, 4, 8, 12, 24, 48 h. Extract plasma with ethyl acetate, evaporate, reconstitute in hexane, and analyze by GC-MS. The half-life is expected to be 6-12 hours. This study assesses systemic exposure, not therapeutic efficacy.
|
| ADME/Pharmacokinetics |
General pharmacokinetic properties: This compound (MW 574.45) is a large, lipophilic molecule (LogP >5). It is poorly soluble in water but soluble in organic solvents. If absorbed, it would distribute to fatty tissues and be metabolized slowly. Elimination half-life may be long (days). For storage, it is a solid, kept at room temperature in a sealed container. Stock solutions in hexane are stable at -20degC for 6 months.
|
| Toxicity/Toxicokinetics |
General toxicity profile: This industrial chemical is a potential irritant and is toxic to aquatic life with long-lasting effects. It may be a weak endocrine disruptor. Standard safety precautions (gloves, lab coat, fume hood) should be used. GHS hazard statements may include H302, H315, H319, H411. For research use only.
