Name: [13C6]-Droxidopa, [13C6]-L-threo-3,4-Dihydroxyphenylserine, [13C6]-L-DOPS, [13C6]-L-threo-DOPS, [13C6]-SM-5688, [13C6]-L-threo-dihydroxyphenylserine, [13C6]-(2S,3R)-2-amino-3-(3,4-dihydroxyphenyl)-3-hydroxypropanoic acid, [13C6]-ß,3-Dihydroxytyrosine

Droxidopa also known as L-DOPS, Lthreo-dihydroxyphenylserine, Lthreo-DOPS and SM-5688 is a synthetic amino acid precursor which acts as a prodrug to the neurotransmitter norepinephrine (noradrenaline). Unlike norepinephrine, droxidopa is capable of crossing the protective blood–brain barrier (BBB).

Stable isotope labeled L-DOPS is intended for use as an internal standard for the quantification of L-DOPS by LC or GC-mass spectrometry.
