Thiolating reagent for primary amines; thiol can be deprotected under mild conditions. Typically, couples initially to a molecule containing primary amine by amide bond buffered at pH 7.5. Deprotection may be accomplished with 0.05 M hydroxylamine at neutral pH. Useful for preparation of enzyme immunoconjugates and hapten carrier molecule conjugates.

Note that the ester couples very efficiently to primary amines compared to other thiolating reagents. In addition, this reagent will neutralize original amine positive charge.

Biochem/physiol Actions

Salicylic acid (SA) delivers local and systemic acquired resistance (LAR and SAR) against various diseases in plants. It acts as a secondary metabolite and regulate various physiological processes such as, seed germination, seedling establishment, cell growth, respiration, stomatal closure and senescence-associated gene expression. In addition, SA also controls abiotic stress, basal thermotolerance, nodulation in legumes and fruit yield. It plays a vital role in modulation of flowering and thermogenesis (heat production) in plants. SA together with reactive oxygen species (ROS) and nitric oxide (NO) triggers cell death in plants.

sec-Butyl methyl ether (2-methoxy butane) is an acyclic methyl ether. It is reported to be formed in trace amounts during the thermal decomposition of meso- and dl-2,3-dimethylsuccinyl peroxides. sec-Butyl methyl ether is prepared by the reaction of sodium sec-butylate and methyl iodide. Its boiling point has been predicted using back-propagation neural network (BP NN).
