Aluminum nitrate nonahydrate is an aluminum salt that can be prepared by dissolving aluminum or aluminum hydroxide in dilute nitric acid. It is used in the preparation of insulating papers, transformer core laminates, and cathode-ray tube heating elements.ApplicationAluminum nitrate nonahydrate can be used as a catalyst to synthesize:· β-Amino carbonyl compounds via one-pot Mannich reaction.· Bis(indolyl)methanes via electrophilic substitution reaction of indoles with aromatic aldehydes.· 3,4-Dihydropyrimidinones via solvent-free Biginelli reaction.

Features and Benefits:· Easily recoverable through simple phase separation· Reusable without a distinct loss of catalytic activity

L(-)-Arabitol ≥99%

Supplier: ALADDIN SCIENTIFIC

L-Arabitol, a rare sugar alcohol, is being studied as a food additive that reduces fat deposits in the intestines. L-Arabitol is used as an inducer of xylanase expression in Hypocrea jecorina (Trichoderma reesei). L-Arabitol is used to identify, differentiate and characterize L-arabitol dehydrogenase(s).

Adipohydrazide ≥99% (by HPLC)

Supplier: ALADDIN SCIENTIFIC

Homobifunctional cross-linking reagent that is specific for aldehydes resulting in relatively stable hydrazone linkages. This is commonly used in the linking of glycoproteins, such as antibodies, in a site specific fashion following periodate oxidation. Oxidation and coupling may conveniently be performed at pH 5.0 due to the low pKa of the hydrazide which avoids competition by primary amines. Note that the hydrazone bond may be stabilized by selective reduction using, for example, sodium cyanoborohydride.

2-Aminobenzyl alcohol ≥98% (by GC)

Supplier: ALADDIN SCIENTIFIC

2-Aminobenzyl alcohol is oxidatively cyclised with an array of ketones in dioxane at 80°C in the presence of a ruthenium catalyst and KOH to give corresponding quinolines.It undergoes oxidation catalyzed by heterotrimetallic RuMnMn species on the hydrotalcite surface in the presence of O2 to yield 2-aminobenzaldehyde.2-Aminobenzyl alcohol was used in the synthesis of ethyl 2-hydroxymethylcarbanilate.
