2-?(2-?Bromoethoxy)?-?4-?methyl-?1-?nitro-benzene is an intermediate in synthesizing N-[2-[2-[2-[Bis(carboxymethyl)amino]-5-(diazoacetyl)phenoxy]ethoxy]-4-methylphenyl]-N-(carboxymethyl)-glycine Tetrapotassium Salt (B416505), which is more stable as dilute aqueous solution since solid form is light sensitive and is susceptible to decomposition. It is used in the photolysis of caged calcium and measurement of calcium concentration in cardiac myocytes.
