1,3-Benzenedicarboxaldehyde, dihydrazone, also known as phthalaldehyde dihydrazone or PdH, is a chemical compound with the molecular formula C10H12N4O2. It is derived from 1,3-benzenedicarboxaldehyde (phthalaldehyde) by reacting it with two equivalents of hydrazine, resulting in the formation of a dihydrazone derivative. 1,3-Benzenedicarboxaldehyde, dihydrazone is a white crystalline solid and is soluble in water, ethanol, and acetone. It is commonly used as a reagent in various analytical techniques, such as the detection and quantification of primary amines, due to its ability to form colored complexes with these amines. Additionally, PdH has applications in the synthesis of other organic compounds and as a building block in the preparation of more complex molecules.

42546-17-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42546-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,4 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 42546-17:
(7*4)+(6*2)+(5*5)+(4*4)+(3*6)+(2*1)+(1*7)=108
108 % 10 = 8
So 42546-17-8 is a valid CAS Registry Number.

Bis-Schiff bases of iosophthalaldehyde were synthesized by reacting isophthalaldehyde with hydrazine hydrate in 1:2 ratio in ethanol for 2-3 h under reflux. Product of first step was again reacted in 1:2 ratio with different aldehyde or acetophenone yield

A novel one pot multi-component strategy for facile synthesis of 5-aryl-[1,2,4]triazolidine-3-thiones

Mane,Pore

supporting information, p. 6601 - 6604 (2015/01/09)

We have disclosed an efficient, one pot, novel multi-component approach for the synthesis of 5-aryl-[1,2,4]triazolidine-3-thiones from aldehyde, hydrazine hydrate, and trimethylsilyl isothiocyanate (TMSNCS) in the presence of catalytic amount of sulfamic acid. High yields, easy work-up procedure, no chromatographic separation, and novelty in multi-component strategy are the main merits of the present strategy.
