3815-86-9 Usage
General Description
Malonic dihydrazide, also known as 1,3-dihydrazinane-1,3-bis(methoxycarbonyl)propane, is a chemical compound with the molecular formula C5H12N4O4. It is a white crystalline solid, and is primarily used as a crosslinking agent in polymer chemistry. It is known for its ability to form stable complexes with metal ions, making it useful in various applications such as chelation therapy and metal ion sensing. Malonic dihydrazide is also used as a precursor in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. Its versatile properties and reactivity make it a valuable building block in organic synthesis and materials science. However, it is important to handle malonic dihydrazide with care, as it is a potential irritant to the skin, eyes, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 3815-86-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,1 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3815-86:
(6*3)+(5*8)+(4*1)+(3*5)+(2*8)+(1*6)=99
99 % 10 = 9
So 3815-86-9 is a valid CAS Registry Number.

The reaction of ethyl 2-oxo-2H-chromene-3-carboxylate with hydrazine hydrate
Abdel-Aziz, Hatem A.,Elsaman, Tilal,Attia, Mohamed I.,Alanazi, Amer M.

Although salicylaldehyde azine (3) was reported in 1985 as the single product of the reaction of ethyl 2-oxo-2H-chromene-3-carboxylate (1) with hydrazine hydrate, we identified another main reaction product, besides 3, which was identified as malono-hydrazide (4). In the last two decades, however, some articles have claimed that this reaction afforded exclusively hydrazide 2 and they have reported the use of this hydrazide 2 as a precursor in the syntheses of several heterocyclic compounds and hydrazones 6. We reported herein a study of the formation of 2 and a facile route for the synthesis of the target compounds N'-arylidene-2-oxo-2H-chromene-3-carbohydrazides 6a-f.
Efficient synthesis of 4-ethoxycarbonyl pyrazolin-5-one derivatives
Jung, Jae C.,Watkins, E Blake,Avery, Mitchell A.
, p. 3767 - 3777 (2007/10/03)
Concise and efficient methods for the preparation of 3-substituted 4-ethoxycarbonylpyrazolin-5-ones are described. The synthetic strategies involve carbon-acylation in the presence of base, followed by ring cyclization with hydrazine or hydrazine monohydrochloride.
