Manufacturing Process
A solution containing 741 g (5.0 mols) of 1 -phenyl-2-propylidenylhydrazine, 300 g (5.0 mols) of glacial acetic acid and 900 cc of absolute ethanol was subjected to hydrogenation at 1,875 psi of hydrogen in the presence of 10 g of platinum oxide catalyst and at a temperature of 30°C to 50°C (variation due to exothermic reaction). The catalyst was removed by filtration and the solvent and acetic acid were distilled. The residue was taken up in water and made strongly alkaline by the addition of solid potassium hydroxide. The alkaline mixture was extracted with ether and the ether extracts dried with potassium carbonate. The product was collected by fractional distillation, BP 85°C (0.30 mm); yield 512 g (68%).The hydrochloride salt was formed in a mixture of 1:10 isopropyl alcohol:diisopropyl ether and recrystallized from acetonitrile, yield 87%, MP 124°C to 125°C.

Check Digit Verification of cas no
The CAS Registry Mumber 55-52-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55-52:
(4*5)+(3*5)+(2*5)+(1*2)=47
47 % 10 = 7
So 55-52-7 is a valid CAS Registry Number.

Page/Page column 11, (2012/05/21)
The present invention relates to a method for the enzymatic hydroamination of C—C double bonds catalyzed by enzymes structurally and/or functionally related to phenylalanine ammonia lyase (PAL) isolated from microorganisms of Petroselinum crispum, Rhodoturula glutinis and/or functional active derivatives thereof.
Azo Anions in Synthesis: α-Amino Carbanion Equivalents from t-Butyldiphenylmethylhydrazones
Baldwin, Jack E.,Adlington, Robert M.,Newington, Ian M.
, p. 176 - 178 (2007/10/02)
α-Amino carbanion equivalents (=C(1-)NH2) and α-hydrazino anion equivalents (=C(1-)NHNH2) are readily accessible from the C-alkylation products of t-butyldiphenylmethylhydrazones; these azoalkanes can be efficiently transformed into amines, hydrazines, and also alkanes under mild reaction conditions.
