10478-99-6 Usage
General Description
2-[4(1H)-pyridinylidene]indan-1,3-dione is a complex chemical compound that belongs to the class of organic compounds known as indandiones. These are compounds containing an indane moiety consisting of a cyclopentane fused to a 1,3-dione. Although the specific applications, properties, or toxicity data of this particular chemical may not be widely documented, indandiones, in general, are typically known to participate in various chemical reactions due to their active carbonyl groups and can be used as intermediates in organic synthesis. These compounds may also have biological activities and could be involved in different bio-chemical or pharmacological processes. However, its specific actions, risks, and applications require further research for confirmation.
Check Digit Verification of cas no
The CAS Registry Mumber 10478-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,7 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 10478-99:
(7*1)+(6*0)+(5*4)+(4*7)+(3*8)+(2*9)+(1*9)=106
106 % 10 = 6
So 10478-99-6 is a valid CAS Registry Number.

Control by one drop of solvent: Selective preparation of guest release/trap-triggered interconvertible molecular crystals
Yakiyama, Yumi,Fujinaka, Takahisa,Nishimura, Mio,Seki, Ryotaro,Sakurai, Hidehiro
, p. 9687 - 9690 (2020)
Interconvertible molecular crystals 1close and 1open composed of 4-pyridyl-1,3-indanedione dimer 1 were selectively obtained. Thermal removal of solvent molecules in 1open afforded 1close. Further dipping of 1close in a specific solvent reproduced 1open. No crystallinity loss was observed even though both processes involved a drastic change of molecular packing arrangements.
Thermal cyclization of 3-azido-2-phenyl-indan-1-one to 5H-indeno[1,2-b]indol-10-one [1]
Stadlbauer, Wolfgang,Fischer, Michaela
, p. 131 - 135 (2002)
3-Azido-2-phenylindan-1-one (4), which was obtained from 3-chloro-2-phenylindan-1-one (3), cyclizes on thermolysis to 5H-indeno[1,2-b]indol-10-one (5). Reaction of 3-azido-2-phenylindan-1-one (4) with triphenylphosphane gives 2-phenyl-3-(triphenylphosphoranylideneamino)-indan-1-one (6), which can be hydrolyzed to 3-amino-2-phenylindan-1-one (7). Attempts to perform a similar cyclization sequence with 3-chloro-2-pyridylindan-1-ones failed.
