GLDA-4Na CAS 51981-21-6 yog dab tsi?

N, N-BIS(CARBOXYMETHYL)-L-GLUTAMIC ACID TETRASODIUM SALT (GLDA-4Na) yog lub teeb daj pob tshab kua. Nws tseem hu ua tetrasodium glutamic acid dicarboxymethyl. Nws lub npe tshuaj yog NN-bis (carboxymethyl)-L-glutamic acid tetrasodium ntsev. Nws yog ib tug tshiab ntsuab chelating tus neeg sawv cev uas yog biodegradable thiab yuav siv tau los hloov ethylenediaminetetraacetic acid (EDTA), diethyltriaminepentaacetic acid (DTPA), nitrogen tsoos chelating agents xws li NTA.
