4-tert-Butylcatechol is usually added as a stabilizer and an inhibitor of polymerization to butadiene, styrene and other reactive monomer streams. It is 25 times higher than hydroquinone at 60 deg C for polymerization inhibitory effect. It is used as a polymerization inhibitor in processing Styrene, Butadiene, and Vinyl Acetate monomers, Polyester resins. Also used as a stabilizer in the manufacture of polyurethane foam. Because of the sterically hindered group, tert-butylphenolic compounds have an antioxidizing action and also act as UV stabilisers. It also can be used as antioxidants for synthetic rubber, polymers and oil derivatives, it can be used as purification agent for aminoformate catalysts. TBC is available in a form of a solid crystal and 85% solution in methanol or water. 4-tert-Butylcatechol inhibits the activity of tyrosinase at concentrations higher than 1×10(−3)M.

Penicillic acid (PA) is a polyketide mycotoxin produced by several species of Aspergillus and Penicillium species showed antibacterial activity against various plant pathogenic bacteria and can be as a lead molecule for the development of synthetic agrochemicals to control plant bacterial diseases. In addition, PA induces single-strand DNA breaks and inhibits DNA synthesis, demonstrating mutagenic and cytotoxic effects. Penicillic acid irreversibly inhibits GDP-mannose dehydrogenase (DMG), an alginate synthesis enzyme, interrupting the committed step in alginate biosynthesis.

Tris(2-carboxyethyl)phosphine or TCEP is a potent, versatile, odorless, thiol-free reducing agent with broad application to protein and other research involving reduction of disulfide bonds. Because TCEP does not contain thiols, it does not have to removed from solutions before performing reactions involving maleimide labeling or cross-linking reagents. TCEP may be used as a substitute for DTT or 2-mercaptoethanol (2-ME) in reducing sample loading buffer for SDS-PAGE. One strategy for labeling antibodies involves reducing disulfide bonds in the hinge region of IgG molecules without also reducing those connecting heavy and light chains.
