Quality Control of Dimethoxydiphenylmethane《A Catalytic Tethering Strategy: Simple Aldehydes Catalyze Intermolecular Alkene Hydroaminations》 was published in 2011. The authors were MacDonald, Melissa J.;Schipper, Derek J.;Ng, Peter J.;Moran, Joseph;Beauchemin, Andre M., and the article was included in《Journal of the American Chemical Society》. The author mentioned the following in the article:

Herein a catalytic tethering strategy in which simple aldehyde precatalysts enable, through temporary intramolecularity, room-temperature intermol. hydroamination reactivity and the synthesis of vicinal N-hydroxy diamines R¹NHCHR²CHMeNR³OH (R¹ = H, Me, H₂C:CHCH₂, PhCH₂; R² = H, Me; R³ = EtCHMe, cyclohexyl, PhCH₂, 2-HOC₆H₄CH₂, 4-MeOC₆H₄CH₂) is described. The catalyst allows the formation of a mixed aminal from an allylic amine R¹NHCHR²CH:CH₂ and a hydroxylamine R³NHOH, resulting in a facile intramol. hydroamination event. The promising enantioselectivities obtained with a chiral aldehyde also highlight the potential of this catalytic tethering approach in asym. catalysis and demonstrate that efficient enantioinduction relying only on temporary intramolecularity is possible. And Dimethoxydiphenylmethane (cas: 2235-01-0) was used in the research process.

The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom.Quality Control of Dimethoxydiphenylmethane

COA of Formula: C15H16O2《A ketal-tethered RCM strategy toward the synthesis of spiroketal related natural products》 was published in 2006. The authors were Ghosh, Sunil K.;Ko, Changhong;Liu, Jia;Wang, Jiashi;Hsung, Richard P., and the article was included in《Tetrahedron》. The author mentioned the following in the article:

An unconventional approach to construct spiroketals and spiroaminals via ring-closing metathesis [RCM] of cyclic ketals and aminals, resp., was described here. This method possesses a good generality with no loss of stereochem. integrity at the spirocenter under the standard RCM conditions. This approach was applied to the synthesis of an insect pheromone I to demonstrate its synthetic potential, and also to the synthesis of the protected C11-epi-C22-C23 fragment II (R = CH₂C₆H₄-4-OMe, R¹ = SiPh₂CMe₃) of spirastrellolide A. Both are proof-of-concept applications to feature a ketal-tethered RCM as an alternative strategy for construction of spiroketals. And Dimethoxydiphenylmethane (cas: 2235-01-0) was used in the research process.

Iacazio, Gilles;Perissol, Claude;Faure, Bruno published 《A new tannase substrate for spectrophotometric assay》. The research results were published in《Journal of Microbiological Methods》 in 2000.Product Details of 2235-01-0 The article conveys some information:

A new tannase substrate, protocatechuic acid p-nitrophenyl ester, I, was synthesized using modern synthetic methods. The synthesis was designed to be performed by non-specialized chemists. It only involves four steps, three of which are protection-deprotection, and uses standard methods of separation and purification, such as recrystallization and column chromatog. over silica. Under tannase action, protocatechuic acid p-nitrophenyl ester, I, releases p-nitrophenol, which is easily measured spectrophotometrically either at 350 nm for pH values < 6 or at 400 nm for pH values of 6-7 (yellow). The pH-response and the catalytic parameters of a crude Penicillium sp. tannase preparation were determined using I as substrate, thus showing the usefulness of this substrate in determining tannase activity. To complete the study, the researchers used Dimethoxydiphenylmethane (cas: 2235-01-0) .
