Import 1-Naa/Na (Pgr) — Buy in Bulk from Supplier in China

1-Naphthylacetic acid sodium salt (CAS 61-31-4), listed here as 1-NAA/Na (PGR), is a systemic auxin-family plant growth regulator. Shanghai Profirst Co., Ltd. supplies this active ingredient from Shanghai in multiple formulation strengths, including 98% technical concentrate and soluble powder grades ranging from 8% to 70% concentration, alongside a 5% soluble liquid. The mode of action relies on uptake through leaves or roots, after which the compound translocates via nutrient flow to growing points, flowers, and fruits, triggering cell division and expansion.

In commercial horticulture, 1-NAA sodium salt is applied to berry crops such as tomato and grape, pome fruits like apple and pear, and cucurbits including watermelon and cucumber. Growers use it as a rooting agent, to prevent premature fruit drop from stems, to thin excess fruit set, and to promote fruit swelling and overall yield. Shanghai Profirst supplies the technical grade (98% TC) for formulators and the ready-to-use soluble powder and liquid concentrations for direct field application. Buyers should confirm minimum order quantities, packaging specifications, and lead times directly with the supplier, as these details are not published on the listing.

Shanghai Profirst Co., Ltd. is based at No. 2, Lane 1123, Kangqiao Road, Pudong New Area, Shanghai 201315, China. The company operates as an imported-tier supplier of agrochemical active ingredients and formulations, with plant growth regulators forming part of its catalogue.
