EINECS No.: 107-92-6
Type: Syntheses Material Intermediates
Application: Fine Intermediate
It is used to determine the critical temperature and surface tension of fat dissolution. When copper is measured by electrolysis, it is used to eliminate the influence of iron. It is also used as an extractant and decalcifier.
Used in the preparation of spices and other organic chemicals, and also in the deliming of leather.

Indole butyric acid
IBA has long been used in agriculture to promote root initiation/growth from plant cuttings. Arabidopsis plants accumulate a detectable amount of IBA. However, little is known regarding the manner in which IBA is synthesized in plants. IBA inhibits primary root elongation and stimulates lateral root formation. Genetic screens for Arabidopsis mutants resistant to exogenous IBA have identified many loci (ibr, IBA resistant). The physiological roles of IBA-derived IAA are difficult to determine because the enzymes responsible for conversion of IBA to IAA (Fig. 2.2) may also participate in other pathways such as peroxisomal fatty acid metabolism. The identification of Arabidopsis IBA resistance (ibr) mutants showed that disruption of the ENOYL-COA HYDRATASE2 (ECH2) gene impairs IBA responsiveness, but appears to leave sugar and fatty acid metabolism unchanged (Strader et al., 2010, 2011). Similarly, a peroxisomal mutant lacking a short chain dehydrogenase/reductase (SDRa) is an ibr mutant (Wiszniewski et al., 2009). Further analysis of ech2 and other ibr mutants demonstrated that IBA-derived IAA plays an important role in root hair and cotyledon cell expansion (Strader et al., 2010, 2011).
To guarantee faster and more uniform rooting, rooting hormones are often used in commercial propagation. Faster rooting reduces exposure to stress and diseases and improves uniformity. Indolebutyric acid (IBA) and naphthalene acetic acid (NAA) are the most used synthetic auxins in plant propagation (Hartmann et al., 1997). More lignified material usually requires higher auxin concentrations than softer material, but high concentrations may also be phytotoxic and decrease rooting (Table 1). Leaves have been shown to have a synergetic effect on the activity of exogenous auxin. In fact, the original leaf needs to be present and photosynthetically active to promote rooting of auxin-treated leafy stem cuttings of R. “Madelon” and R. “Sonia” because leafless or covered leaf cuttings or cuttings propagated in darkness failed to root and/or were affected by stem rot
