This page covers the substance itself. Commercial grades and physical forms — which differ in particle size, purity tier and production route — are described on the corresponding catalogue page.

Chemical and regulatory data below are generated from public reference sources by the site engine and are keyed to the CAS number.

Two grades on one ladder. Pack sizes from 100 g to 25 kg are supplied as laboratory grade (typically ≥99 % p.a. / ACS / Ph. Eur.), where the price is dominated by packaging, quality control and handling rather than by material. Tonnage quantities are supplied as technical grade and priced on a commodity basis. The price per kilogram therefore drops sharply between the 25 kg and 1 t steps — these are different products, not a pricing error.
