α-Terpineol is a monoterpene alcohol. It is one of the components responsible for the antifungal activity in Melaleuca alternifolia (tea tree) essential oil.[1] The reaction rate constant of α-terpineol with the OH radical and ozone was found to be (1.9±0.5)×10-10cm3 molecule-1s-1 and (3.0±0.2)×10-16cm3 molecule-1s-1, respectively.Application:α-Terpineol has been used as a reference standard for the identification of α-terpineol in tequila by solid phase microextraction (SPME) and capillary gas chromatography−mass spectrometry (GC-MS), and in virgin olive oil samples by headspace SPME followed by GC-MS equipped with flame ionization detector (FID).It may be used as a reference standard for the analysis of α-terpineol as trace volatile compound in wine by solid-phase extraction (SPE) followed by GC-MS and in essential oils and related compounds from aromatic plants by SPME and GC-MS.α-Terpineol may be used in the synthesis of α-terpinyl esters of acetic acid and acetic anhydride via lipase-mediated esterification.

GABPB2 is the GA-binding protein transcription factor, beta subunit. This protein forms a tetrameric complex with the alpha subunit, and stimulates transcription of target genes. The protein may be involved in activation of cytochrome oxidase expression and nuclear control of mitochondrial function. The crystal structure of a similar protein in mouse has been resolved as a ternary protein complex. Multiple transcript variants encoding distinct isoforms have been identified for this gene. This gene encodes the GA-binding protein transcription factor, beta subunit. This protein forms a tetrameric complex with the alpha subunit, and stimulates transcription of target genes.

Ethyl Acetate is an organic solvent with the structure CH₃-COO-CH₂-CH₃ (C₄H₈O₂). This colorless liquid has a characteristic sweet odor. In the laboratory, mixtures containing ethyl acetate are used in column chromatography and extractions. Ethyl acetate does not work well as a reaction solvent because it is prone to hydrolysis and transesterification. Ethyl acetate is volatile at room temperature and has a boiling point of 77 °C. Suitable for GC and Pesticide Residue Analysis.

Sodium azide used as a preservative for laboratory reagents; a bacteriostatic agent in storage solutions. Inhibits gram negative flora so is therefore included in culture media for the selective isolation of Streptococci and Staphylococci. It has been used to avoid bacterial contamination during RPC-5 column chromatography of DNA fragments.
Catalyst for:
• Oxidative decarboxylation
• Michael addition reactions
Reagent for synthesis of
• Blue fluorescent copolymers
• Metal phosphonates
• Arenes via aminations
Involved in regioselective synthesis of prianosin B
It is also a useful probe reagent, mutagen, and preservative. In hospitals and laboratories, it is a biocide (A biocide is a chemical substance or microorganism which can deter, render harmless, or exert a controlling effect on any harmful organism by chemical or biological means.)
Sodium Azide is an inhibitor of peroxidase, myeloperoxidase, superoxide dismutase, galactose oxidase, catalase, haemoprotein enzymes and O2 evolution in photosynthesis. The mechanism of its inhibition and toxicity may be due to metal ion complexation and displacement from enzyme.
