5-Bromodeoxyuridine

Product name: 5-Bromodeoxyuridine
CAS: 59-14-3
Molecular Formula: C9H11BrN2O5
Formula Weight: 307.1
Description:
Bromodeoxyuridine (5-bromo-2-deoxyuridine, BrdU) is a synthetic nucleoside, which is a thymidine analogue. BrdU is usually used in the detection of proliferating cells in living tissues.
BrdU can be incorporated into the newly synthesized DNA of replication cells (during the S phase of the cell cycle), said thymidine is used during DNA replication. Specific BrdU antibodies can then be used for the integrated chemical (see immunohistochemistry) to detect and display cells that actively replicate their DNA. The binding of the antibody requires the denaturation of the DNA, usually by exposing the cells to acid or heat.
Because BrdU can replace thymidine during DNA replication, it can cause mutations, and therefore its use can be a health risk.

1,1-Dimethylhydrazine

Product Name: 1,1-Dimethyl Hydrazine
CAS: 57-14-7
Molecular formula: C2H8N2
Formula Weight: 60.1
Description:
Dissymmetric dimethylhydrazine (UDMH) (1,1-dimethylhydrazine) is a volatile toxic, hygroscopic liquid with a strong clear, fish-like, ammoniacal odor that is typical of organic amines. It is yellowish when exposed to air and absorbs oxygen and carbon dioxide.
UDMH is often used in hyperpolar bipropellant rocket fuels only in combination with the oxidizing agent and nitrogen tetroxide less frequently with IRFNA (red fuming nitric acid) or liquid oxygen. UDMH is a derivative of hydrazine, and is sometimes called hydrazine. As fuel in specification MIL-D-25064 is described.
