Benzo[1,2-b:4,5-b’]dithiophene-4,8-dione

CAS 32281-36-0, Benzo[1,2-b:4,5-b’]dithiophene-4,8-dione, is a C10H4O2S2 heterocycle supplied in kilogram lots, stock or made to order.

Heterocycles of this substitution pattern are carried through several steps, which makes residual metal content of the lot the number that decides whether the step works. The ring constrains the geometry of the fragment, so the entry is bought for the shape it imposes on the rest of the molecule rather than for a single reactive site.

The formula C10H4O2S2 resolves to 10 carbons with 2 oxygens and 2 sulfurs. A 10-carbon chain sits between volatility and lipophilicity, which is the range most often used when a fragment has to stay in the organic phase without being waxy.

Handling and storage

Heterocycles are stored dry and out of light; several of the entries in this group are light sensitive.

Ordering

The unit weights held are 1kg / 25kg / 100kg. A split shipment across two of those sizes is treated as one lot and one certificate. Where a specification has to be met on paper before shipment, it is agreed in writing and the lot is qualified against it rather than against the catalogue text.
