TCI D6417 is Dihydrozeatin, a naturally occurring plant hormone belonging to the cytokinin class and representing the reduced form of zeatin. Cytokinins play an essential role in regulating cell division, shoot formation, and the delay of leaf senescence in plants. In the laboratory, this compound is used primarily as a plant growth regulator in plant tissue culture media, and as a test substance in plant molecular biology research investigating the mechanisms by which hormone signals are perceived and transmitted within the cell.
The characteristic that distinguishes dihydrozeatin from zeatin is its saturated side chain, which contains no double bond. This small structural difference makes the molecule more resistant to breakdown by cytokinin oxidase/dehydrogenase, the enzyme responsible for inactivating cytokinins within plant tissue. As a result, hormone activity can persist longer in both the culture medium and the tissue itself, which is valuable when researchers require a stable signal to be delivered throughout the culture period. As a naturally occurring cytokinin, the compound also serves as an important comparator when evaluating plant responses to synthetic cytokinins such as kinetin or benzyladenine.
In Indonesia, this material is widely required by laboratories working in plant tissue culture and plant molecular biology, including university research laboratories, agricultural and plantation research institutes, and plant propagation facilities. It supports both routine micropropagation work and fundamental research into cytokinin signalling. Because it is supplied by TCI under the catalogue reference D6417, laboratories can specify it consistently across repeated orders and across different research groups working on related plant hormone studies.

- Plant tissue culture media supplementation — added as a plant growth regulator to promote cell division and shoot formation during in vitro propagation of plant material.
- Cytokinin signalling research — used as a test substance in plant molecular biology studies that examine how hormone signals are perceived and transmitted inside the plant cell.
- Extended-duration culture experiments — its resistance to cytokinin oxidase/dehydrogenase allows hormone activity to persist longer, supporting stable signal delivery throughout the culture period.
- Comparative hormone studies — serves as a naturally occurring cytokinin reference when comparing plant responses against synthetic cytokinins such as kinetin or benzyladenine.
- Shoot induction and senescence studies — applied in experiments investigating shoot formation and the delay of leaf senescence, both processes regulated by cytokinin activity in plants.

Store the product in its original, tightly closed manufacturer container, following the storage conditions indicated on the product label and accompanying documentation. Keep the container protected from moisture and direct light, and allow it to reach room temperature before opening to reduce condensation on the contents. Handle the material in a clean working area using a laboratory coat, gloves, and eye protection, and weigh it using clean, dry spatulas to avoid cross-contamination of the stock. When preparing solutions for culture media, work under aseptic conditions, label all prepared stocks clearly with the compound name and preparation date, and store prepared solutions as required for the intended experimental work. Dispose of residues and contaminated consumables in accordance with the laboratory's chemical waste procedures.
