2. The chromatography matrix of claim 1, wherein:
X is selected from the group consisting of —O—CH2—, —O—CH2—CH2—, —O—CH2—CH2—CH2—, —O—CH2—CH2—CH2—CH2—, —O—CH2—CH(CH2—OH)—(O—CH2—CH(OH)—CH2)2—, —O—CH2—CH2—CH(CH2—OH)—(O—CH2—CH2—CH(OH)—CH2)2—, —O—CH2—CH(OH)—CH2—, —O—CH2—CH2—CH(OH)—CH2—CH2—, —O—CH2—CH(OH)—CH2—O—CH2—CH2—CH2—CH2—O—CH2—CH(OH)—CH2—, and —CO—NH—C(CH3)2—CO—;
R1 is hydrogen or C1 to C3 alkyl;
R2 is C2 to C4 alkyl;
L is O;
n=1; and
Ar is a 6 membered ring and:
if Ar is aryl, the aryl is optionally substituted with up to four C1 to C2 unsubstituted alkyl, C3 or C4 branched alkyl, or fluorine groups; or
if Ar is heteroaryl, the heteroaryl is optionally substituted with up to three unsubstituted alkyl groups,
with the proviso that when R1 is hydrogen, R2 is C2 alkyl, and n is 1, Ar is not phenyl.
