Hydroxylamine, O-(diphenylmethyl)-, also known as O-(Diphenylmethyl)hydroxylamine or DPM-Hydroxylamine, is an organic compound with the chemical formula C13H13NO. It is a colorless to pale yellow crystalline solid that is soluble in common organic solvents such as ethanol, acetone, and dichloromethane. Hydroxylamine, O-(diphenylmethyl)- is primarily used as a protecting group in organic synthesis, particularly for amines, due to its stability and ease of removal under mild acidic conditions. It is also employed as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. The compound is sensitive to light and moisture, and it is recommended to store it in a cool, dry place, protected from light.

1782-38-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1782-38-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,8 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1782-38:
(6*1)+(5*7)+(4*8)+(3*2)+(2*3)+(1*8)=93
93 % 10 = 3
So 1782-38-3 is a valid CAS Registry Number.

Chiral integrated catalysts composed of bifunctional thiourea and arylboronic acid: Asymmetric aza-Michael addition of α,β-unsaturated carboxylic acids

Hayama, Noboru,Azuma, Takumi,Kobayashi, Yusuke,Takemoto, Yoshiji

, p. 704 - 717 (2016/07/19)

The first intermolecular asymmetric Michael addition of nitrogen-nucleophiles to α,β-unsaturated carboxylic acids was achieved through a new type of arylboronic acid equipped with chiral aminothiourea. The use of BnONH2 as a nucleophile gives a range of enantioenriched β-(benzyloxy)amino acid derivatives in good yields and with high enantioselectivity (up to 90% yield, 97% enantiomeric excess (ee)). The obtained products are efficiently converted to optically active β-amino acid and 1,2-diamine derivatives.

2-[(arylmethoxy)imino]imidazolidines with potential biological activities

Saczewski, Jaroslaw,Hudson, Alan L.,Rybczynska, Apolonia

experimental part, p. 671 - 680 (2010/07/04)

A series of 2-[(arylmethoxy)imino]imidazolidines was synthesized by reacting 2-chloro-4,5-dihydroimidazole with corresponding O- arylmethylhydroxylamines and evaluated for their α1-, α2-adrenergic and imidazoline I1, I2 receptor binding affinities. The most potent 2-[(naphthalen-1-ylmethoxy)imino] imidazolidine showed a high selectivity and good affinity for the [ 3H]prazosin-labeled α1-adrenoceptors (Ki = 107 nM). Representative compounds of this series were also tested in vivo for possible circulatory effects in rats after intravenous administration.

Factors Affecting the Stability and Equilibria of Free Radicals. XIII. N-Alkoxy- and N-Aralkoxypicrylamines and ESR Spectra of the Corresponding Capto-Dative Persistent Aminyls

Stanciuc, Gabriela,Caproiu, M. Teodor,Caragheorgheopol, Agneta,Caldararu, Horia,Balaban, Alexandru T.,Walter, Robert I.

, p. 63 - 72 (2007/10/02)

Five O-alkylhydroxylamines and three aralkylhydroxylamines have been picrylated to give O-alkyl-N-picrylhydroxylamines.These were converted to the corresponding N-(ar)alkoxy-picryl-aminyl radicals in toluene solution, and the ESR spectra were recorded.Simulations of the spectra with reasonable parameters and g values confirm the expected radical structures.Hyperfine coupling constants for nuclei in the picryl (acceptor) ring are smaller than those for the (ar)alkoxy group.This indication of competitive electron pair delocalization to the picryl ring, together with the long lifetimes of these radicals (compared with the symmetrically substituted diphenylaminyls), both support the concept of captodative stabilization.
