19298-72-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19298-72-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,9 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19298-72:
147 % 10 = 7
So 19298-72-7 is a valid CAS Registry Number.

Solid-state linear polarized IR-spectroscopic and theoretical analysis of methioninamide (cas 19298-72-7) ester amide of squaric acid diethyl ester07/31/2019

Methioninamide ester amide of squaric acid (1) has been analyzed structurally and IR-spectroscopically by means of ab initio calculations and solid-state linear-polarized IR-spectroscopy (IR-LD) of oriented solid-samples as suspension in nematic liquid crystal. The obtained data are compared wit...detailed

The invention refers to the use of a particulate catalyst containing 60.0 to 99.5 wt.% ZrO2 stabilised with an oxide of the element Hf and at least one oxide of the element M, wherein M = Ce, Si, Ti, or Y, for the hydrolysis reaction of methionine amide to methionine, wherein the median particle size x50 of the particulate catalyst is in the range of from 0.8 to 9.0 mm, preferably of from 1.0 to 7.0 mm. The invention also refers to a process for preparing methionine comprising a step of contacting a solution or suspension comprising methionine amide and water with said particulate catalyst to provide a reaction mixture comprising methionine and/or its ammonium salt from which methionine can be isolated.

Carbohydrates as efficient catalysts for the hydration of α-amino nitriles

Chitale, Sampada,Derasp, Joshua S.,Hussain, Bashir,Tanveer, Kashif,Beauchemin, André M.

supporting information, p. 13147 - 13150 (2016/11/09)

Directed hydration of α-amino nitriles was achieved under mild conditions using simple carbohydrates as catalysts exploiting temporary intramolecularity. A broadly applicable procedure using both formaldehyde and NaOH as catalysts efficiently hydrated a variety of primary and secondary susbtrates, and allowed the hydration of enantiopure substrates to proceed without racemization. This work also provides a rare comparison of the catalytic activity of carbohydrates, and shows that the simple aldehydes at the basis of chemical evolution are efficient organocatalysts mimicking the function of hydratase enzymes. Optimal catalytic efficiency was observed with destabilized aldehydes, and with difficult substrates only simple carbohydrates such as formaldehyde and glycolaldehyde proved reliable.
