high-purity ippd-quinone reference materials for accurate,discover the precision and reliability of our high-purity ippd-quinone reference materials, designed for meticulous residue analysis. as a crucial antioxidant in the rubber industry, ippd-quinone requires stringent monitoring to comply with international safety standards.
in this study, we developed a stable, rapid, and sensitive analytical method combining salt-out-assisted extraction, antioxidant protection, and m-pfc clean-up to determine ppds and their tps (6ppd, ippd, 6ppd, ippdq, 4-adpa, 4-hdpa, and 4-ndpa) in aquatic products.
widely used chemical rubber antioxidant ippd
N-Isopropyl-N'-phenyl-p-phenylenediamine (often abbreviated ippd) is an organic compound commonly used as an antiozonant in rubbers. like other p-phenylenediamine-based antiozonants it works by virtue of its low ionization energy, which allows it to react with ozone faster than ozone will react with rubber. [2]
the effect of antioxidant concentration of n-isopropyl-n,study the influence of high concentrations of antioxidants n-isopropyl-n-phenyl-p-phenylenediamine (ippd) and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq) and the mixing time of the vulcanization physical properties, thermal properties, mechanical properties and structure micro on natural rubber compound has been done.
on the dehydrogenation of n,n′-substituted p-phenylenediamine
using b3lyp/6-31g ∗ treatment, the optimal geometries, electronic structures and ir spectra of n-phenyl-n′-isopropyl-p-phenylenediamine antioxidant (ippd) and its doubly dehydrogenated oxidation products have been obtained.
new evidence of rubber-derived quinones in water, air for sale,mixed antioxidants composed of antioxidant ippd and novel rare earth lanthanum complex were used as an additive to prep. natural rubber (nr) samples.
ippd antioxidant 4010na|n-isopropyl-n`-phenylenediamine
application: antioxidant ippd is a kind of polluting anti-oxidation agent in various rubbers. it has good performance for oxygen and ozone resistance, flexible and crack resistance, cracks by sunlight and inhibition of harmful metal ions like copper and manganese.
ippd (cas 101-72-4) cayman chem,ippd is an aromatic amino antioxidant and antiozonant. 1,2 it reduces the activity of superoxide dismutase (sod) and catalase (cat) in zebrafish larvae. 1 ippd (300 µg/l) reduces heart rate and induces cardiac malformations in zebrafish embryos, and it reduces the swimming speed of zebrafish larvae when used at concentrations of 2 and 300 µg

Rubber Antioxidant 6PPD Antioxidant 4020 CAS 793-24-8,considering the similar chemical structure of 6ppd to other widely applied ppds (e.g., ippd and dppd), toxic effects of human exposure to various ppds have attracted scientific concerns (hua and wang, 2023; xu et al., 2022).
- Can antioxidant protection be used to detect PPDS and TPS?
- An efficient and stable method for the detection of PPDs and their TPs was developed. Oxidative degradation is the main cause of low extraction efficiency of PPDs and some TPs. Combined strong antioxidant protection for stable extraction PPDs and their TPs was first proposed.
- Are Roadside soil dust and PPD-QS harmful to humans?
- As shown in Figure 3, the daily intake doses of PPD-Qs are estimated to be 1.08 ng/ (kg·day), which exceeded the doses from their parent compounds [0.71 ng/ (kg·day)] under the same exposure scenarios. The results indicated that ingestion of roadside soil dust was the main contributor to human exposure of PPDs and PPD-Qs.
