Structure of [2H5] trans-zeatin Skeletal formula of trans-zeatin with five deuterium atoms on the methyl and hydroxymethyl groups of the side chain, highlighted. N N N N H HN CD2 CD3 OH
[2H5] trans-Zeatin (D-tZ)
Catalogue no.
030 0301 (1 mg), 030 0302 (2 mg), 030 0303 (5 mg)
Molecular weight
224.28
Mass shift
+5 against natural trans-zeatin (219.24)
Purity
> 98 % (HPLC)
Five deuterium atoms make the standard five mass units heavier than the natural cytokinin. Added to a plant extract, it lets mass spectrometry measure the hormone against a known amount of itself.

Six product lines for plant hormone research

Pack sizes from 1 mg. For larger amounts than listed, ask for a quotation.

A plant hormone company from Olomouc

OlChemIm was founded in 1991 to produce high-quality cytokinins and their immunoreagents. Today it supplies plant growth regulators, their labelled derivatives and antibodies to laboratories around the world.

The company builds on more than a century of Czech plant physiology, from Bohumil Němec, who explained root gravitropism, to Rudolf Dostál, founder of Czechoslovak research on plant hormones.
