CAS 10222-01-2 corresponds to 2,2-dibromo-2-cyanoacetamide (commonly known as DBNPA 99% 20%), which is a broad-spectrum, non oxidizing organic bromine industrial fungicide and algaecide with the molecular formula C ∝ H ₂ Br ₂ N ₂ O and a molecular weight of 241.87.

Core identification and physicochemical properties
-Chinese name: 2,2-dibromo-2-cyanoacetamide (also known as dibromocyanoacetamide, 2,2-dibromo-3-nitrosopropynamide, etc.)
-English name: 2,2-dibromo-2-cyanoacetamide
-Molecular formula/molecular weight: C ∝ H ₂ Br ₂ N ₂ O/241.87
-Appearance: White crystalline powder or crystal
-Melting point: 122-126 ℃
-Solubility: Slightly soluble in water (about 1.5g/100g at 25 ℃), easily soluble in organic solvents such as acetone, ethanol, benzene, DMF, etc
-Stability: Stable under acidic conditions; Easy to decompose and fail when exposed to alkali, high temperature, light or reducing agents (such as hydrogen sulfide)

Main purpose and mechanism of action
-Application areas: Industrial circulating cooling water, papermaking pulp, metalworking fluids, coatings, wood preservation, and sterilization, algae removal, and sludge stripping for oilfield water injection systems.
-Mechanism of action: Quickly penetrate microbial cell membranes, block redox reactions, and selectively brominate/oxidize key enzyme metabolites, leading to cell death; It also has the function of stripping biofouling.
-Application characteristics: quick onset, no foam, low concentration and high efficiency (usually 10 – 20 mg/L for impact dosing), which can be used together with chlorine based oxidants.

Safety and Storage
-Toxicity: Moderate toxicity (oral LD ₅₀ about 118 mg/kg in rats), irritating to the skin, eyes, and respiratory tract.
-GHS classification: Signal word Danger, hazards include skin corrosion/irritation, severe eye damage, and aquatic toxicity.
-Storage requirements: Seal and store in a cool (≤ 30 ℃), dry, and well ventilated place. Do not mix with alkalis, strong oxidants, and reducing agents, and avoid direct sunlight.
