H2so4

Manufactured by AppliChem

H2SO4 is a clear, colorless, and odorless liquid that is widely used in various industrial and laboratory applications. It is a strong mineral acid that is highly corrosive and can cause severe burns if not handled properly. H2SO4 is a key component in many chemical processes and is commonly used in the production of fertilizers, pharmaceuticals, and other chemicals.

OFL, ENR, and SAR (Table 1) of high purity (>99%)
and catalase (lyophilized powder from bovine liver 2000–5000
units/mg protein) were purchased from Sigma-Aldrich. Na₂SO₃ anhydride (85–90%), FeSO₄·7H₂O, H₂O₂ (33% w/v), ascorbic acid, 1,10-phenanthroline
1-hydrate, H₂SO₄ (96% w/w), and UHPLC-grade
methanol and acetonitrile were obtained from AppliChem-Panreac. Formic

prepared with a Merck Milli-Q system. The zone of inhibition tests
was made using E. coli CECT 101 strain,
employing tryptone soya and Mueller–Hinton broth, both provided
by Scharlau.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
