| Analysis Note: | These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available. |
| Application: | Propyl gallate may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and fatty liquids by chromatography and spectrophotometry. |
| Application: | These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements. |
| Application: | Used as an anti-fade reagent in fluorescence microscopy to reduce photobleaching of fluorescent probes such as rhodamine and fluorescein. |
| Biochem/physiol Actions: | An antioxidant that exhibits antimicrobial activity. Propyl gallate has been reported to be an effective antioxidant-based hepatoprotector, both in vitro and in vivo. It has also been shown to prevent neuronal apoptosis and block the death of neurons exposed to FeSO4/GA as well as partially protect endothelial cells against TNF-induced apoptosis. |

It has also been shown to prevent neuronal apoptosis and block the death of neurons exposed to FeSO4/GA as well as partially protect endothelial cells against TNF-induced apoptosis. However, propyl gallate induced single strand breaks in DNA at concentrations higher than 0.25 μM when it was combined with copper concentrations at 5 μM and above. Another report, however, found that incubation of isolated rat hepatocytes with propyl gallate at concentrations of >1 mM induced cell killing, whereas, a lower concentration of propyl gallate > 0.5 mM resulted in a ladder formation of soluble low-molecular weight DNA fragments, characteristic of apoptosis. |

| General description: | Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Propyl gallate is a synthetic phenolic antioxidant (SPA) utilized in food additives to inhibit or regulate the lipid oxidation. SPAs are cost-effective, largely available and highly efficient in comparison to their natural counterparts. |
