Sodium 2-formylbenzenesulfonate is an important aromatic sulfonate fine chemical intermediate with active aldehyde group and stable sulfonic acid sodium group. It is the core raw material for synthesizing fluorescent whitening agent CBS series products, which are widely added into washing powder, detergent, textile fabrics and papermaking industry to effectively improve product whiteness and brightening effect. It is also widely used in the synthesis of triphenylmethane dyes, acid dyes and basic dyes, and plays a key role in textile printing and dyeing, leather coloring and ink coloring fields. In addition, it can be used to prepare wool anti-moth finishing agents and daily chemical functional additives. In organic synthesis field, it can participate in condensation reaction, addition reaction and cyclization reaction, and is used to develop pharmaceutical intermediates, water-soluble polymer materials and metal chelating agents. Its excellent water solubility makes it suitable for various water-phase synthesis processes, greatly simplifying post-treatment steps and improving production efficiency. With stable chemical performance and moderate reaction activity, this product has become an indispensable basic intermediate in dye industry, daily chemical industry and organic synthesis industry, and has stable market supply and wide downstream application space.

This chemical is low toxic and weakly irritating daily chemical intermediate. Inhalation of its dust will cause slight irritation to nasal cavity and respiratory tract, resulting in dry throat and mild cough, so operators need to keep working environment well ventilated and wear simple dust-proof masks. Direct long-term skin contact may cause local skin dryness, redness and slight itching discomfort, please wear chemical protective gloves during operation and clean skin with running water in time after contact. Once splashed into eyes, it will cause obvious eye irritation, tearing and foreign body sensation, immediately rinse eyes with plenty of clean flowing water for more than fifteen minutes and seek medical treatment if discomfort persists. Accidental ingestion may cause mild gastrointestinal symptoms such as nausea and stomach distension, drink enough warm water to relieve symptoms and avoid taking irritant food. The product is non-flammable and non-explosive, but high temperature heating will cause decomposition and release harmful sulfur-containing gas. It shall be stored separately from strong oxidants and corrosive chemicals. After operation, thoroughly clean working tools and work site. All waste materials and waste liquid shall be treated in accordance with local environmental protection standards to prevent unnecessary environmental pollution and personal health damage.
