TCI N0007 Sodium 1-Naphthaleneacetate, bearing CAS number 61-31-4, is the sodium salt of 1-naphthaleneacetic acid and one of the most widely used forms of synthetic auxin in plant biotechnology work. The compound combines the biological activity of the naphthaleneacetate skeleton with the convenient handling characteristics of an inorganic salt. In the laboratory, its role is that of a plant growth regulator added to culture media to direct the development of explants, as well as a treatment solution in plant physiology experiments, propagation trials, and post-harvest research.
The properties that make this material a preferred choice begin with its good solubility in water, which allows stock solutions to be prepared quickly without organic solvents and without any heating step. As a solid, the material is stable under ordinary storage conditions and is easy to weigh out in the small quantities required for media formulated at milligram-per-litre auxin concentrations. Because it is already present in ionised form, it mixes homogeneously with the mineral salt components of basal media without producing turbidity. Its aromatic skeleton also confers resistance to enzymatic degradation within plant tissue, so the effect it produces is sustained.
In Indonesian laboratories, this product is typically encountered wherever plant tissue culture and plant biotechnology are practised: university teaching and research laboratories, agricultural and plantation research institutes, and commercial micropropagation facilities. It is normally kept alongside other growth regulators as part of the standard media-preparation inventory, drawn on for routine subculture schedules, and used in physiology and post-harvest studies where a reproducible, water-soluble auxin source is required for solution treatments.

- Plant tissue culture media preparation: added as the auxin component of basal culture media, where its ready solubility and ionised form let it disperse evenly among the mineral salts without turbidity.
- Explant growth direction and subculture work: supplied to culture media to steer the developmental response of explants, with the stability of the aromatic skeleton giving a sustained rather than short-lived effect.
- Plant physiology experiments: applied as a treatment solution in studies of growth regulation, since aqueous stock solutions can be made up rapidly and accurately at low working concentrations.
- Propagation and nursery research: used in seedling and propagation trials as a defined synthetic auxin source that is easy to weigh in small amounts for reproducible treatment series.
- Post-harvest research: employed as a treatment solution in post-harvest studies, where its resistance to enzymatic degradation in plant tissue supports a consistent and prolonged regulatory effect.

Store the solid in its original tightly closed container under ordinary laboratory storage conditions, in a dry place away from direct sunlight and moisture, since the material is stable in this form and requires no special cold handling for the solid state. Use clean, dry spatulas and weighing vessels when dispensing the small quantities needed for milligram-per-litre media, and prepare aqueous stock solutions in clean glass or suitable plastic bottles that can be closed and clearly labelled with the concentration and preparation date. Keep prepared stock solutions refrigerated and protected from contamination, particularly when they will be used for sterile culture work. As with any laboratory chemical, handle with gloves, a laboratory coat, and eye protection, work in a well-ventilated area, avoid generating dust when weighing the powder, and wash hands after handling. Consult the manufacturer's safety data sheet before use and dispose of residues according to local laboratory waste procedures.
