Uses

Formaldehyde Sodium Bisulfite(870-72-4) is used in the preparation of oil-soluble sulfonate additives used in improving anticorrosive, dispersant and antioxygenic properties of lubricant oils. Also used in chemical reactions in the preparation of chiral salen Mn(III) catalysts or lignosulfonates as dispersant for gypsum paste.

Uses

Formaldehyde sodium bisulfite(870-72-4), is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and Dyestuff. It also acts as an pharmaceutical intermediate. It can effectively complex metal ion such as Cu, Zn, Pb, co-depositing with nickel ion.

Application

Formaldehyde sodium bisulfite(870-72-4) is used in photography (developer) and protects colour pictures exposed to high humidity from fading and staining. It is also used as a textile stripping agent, a colour-fixing agent for keratin-containing fibres, a flotation agent in lead and zinc ores, a preservative in cosmetics and a fungicide in mushroom cultivation. In addition, it is used in foaming agent compositions for civil engineering.

General Description

Formaldehyde-sodium bisulfite adduct(870-72-4) is used as a standard in the synthesis of 3-Hydroxypropionaldehyde (3HPA). It can be assayed by HPLC with fluorometric detection in selected foods.
