1,4-Methanonaphthalene-5,8-diol, 1,2,3,4,9,9-hexachloro-1,4-dihydro-, also known as Hexachloro-1,4-dihydro-1,4-methanonaphthalene-5,8-diol, is a chemical compound with the molecular formula C10H4Cl6O2. It is a derivative of naphthalene, a polycyclic aromatic hydrocarbon, with six chlorine atoms and two hydroxyl groups attached to the molecule. 1,4-Methanonaphthalene-5,8-diol, 1,2,3,4,9,9-hexachloro-1,4-dihydro- is characterized by its hexachloro substitution, which significantly alters its physical and chemical properties compared to the parent naphthalene structure. It is important to note that due to the presence of multiple chlorine atoms, 1,4-Methanonaphthalene-5,8-diol, 1,2,3,4,9,9-hexachloro-1,4-dihydro- may exhibit persistent, bioaccumulative, and toxic characteristics, which are of environmental and health concern. The compound's specific applications and safety considerations should be carefully evaluated, as chemicals with such properties are often subject to regulatory controls to minimize their impact on the environment and human health.

Check Digit Verification of cas no

The CAS Registry Mumber 5210-87-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5210-87:
(6*5)+(5*2)+(4*1)+(3*0)+(2*8)+(1*7)=67
67 % 10 = 7
So 5210-87-7 is a valid CAS Registry Number.

A simple procedure for preparing annulated p-benzoquinones. Improved synthesis of 1,4-dihydro-1,4-methanonaphthalene-5,8-dione

Marchand,Alihodzic,Shukla

, p. 541 - 546 (2007/10/03)

A simple and efficient two-step, one-pot synthesis of substituted 1,4-dihydro-1,4-methanonophthalene-5,8-diones is reported. This synthesis, which utilizes readily available starting materials and inexpensive reagents, can be used to prepare 1a-1c in 70-90% overall yield. This procedure was extended successfully to prepare a more highly complex annulated p-benzoquinone i.e., 8.

Some compounds along the pathway to unsymmetrically substituted secopentaprismanes

Sun, Duoli,Watson, William H.

, p. 721 - 737 (2007/10/03)

In the preparation of an unsymmetric, polyfunctional [5]-secoprismane hexachlorocyclopentadiene and 5,5-dimethoxy-1,2,3,4-tetrachlorocyclopentadiene were added sequentially to benzoquinone via Diels-Alder reactions. At one point oxidation of the hydroquinone of the diadduct is necessary, and cerium (IV) ammonium nitrate (CAN) is a common oxidizing agent. Oxidation of the diadduct with CAN led to cleavage of the dimethoxy bridge forming a substituted naphthoquinone. The structures of five Diels-Alder adducts and two reaction products of the naphthoquinone are discussed.

The known compound, 1,2,3,4,9,9-hexachloro-1,4-dihydro-1,4-methanonaphthalene-5,8-diol (I) is an excellent flame retardant for ABS resins and polyurethanes, particularly, polyether-based polyurethanes. Compound (I) also forms novel molecular complexes with weak bases such as pyridine, pyridine HCl, pyridine oxide, dimethylsulfoxide and dimethylformamide, and which are excellent flame retardants for ABS resins. Compound (I) also exhibits unusual synergistic flame retardant effects in ABS resins and other polymers when used together with certain additives that are not themselves flame retardants.
