FAQ - Technical & Supply Chain
-
Q:
Is BTA the same as 1H-Benzotriazole?
A: Yes. BTA is the common abbreviation for 1H-Benzotriazole, also called Benzotriazole or 1,2,3-Benzotriazole. The CAS number is 95-14-7, and the compound has molecular formula C₆H₅N₃. -
Q:
Which specifications matter for Benzotriazole?
A: Compare assay, appearance, melting range, moisture or loss on drying, color and related isomers or impurities. Typical BTA is a white to light yellow crystalline solid with a melting range around 96-100 °C, but the required limits depend on whether it is used as a corrosion inhibitor or as a synthesis intermediate. -
Q:
What is 1H-Benzotriazole used for?
A: BTA is used mainly as a corrosion inhibitor or passivator for copper and copper alloys in circulating cooling water, antifreeze, aircraft deicing fluids, metalworking fluids and lubricants. It is also used in water treatment, photographic restrainers, analytical silver testing, and as an intermediate or UV-related stabilizing component in selected formulations. -
Q:
How should BTA be stored and handled?
A: Store in tightly closed containers in a cool, dry, ventilated area away from heat, ignition sources, strong oxidizers and incompatible materials. Minimize dust generation, avoid inhalation and skin or eye contact, and use adequate ventilation and appropriate chemical protective equipment. -
Q:
What are the key physical properties of 1H-Benzotriazole?
A: BTA is a white to light yellow crystalline solid with molecular formula C₆H₅N₃ and molar mass about 119.13 g/mol. It typically melts around 96-100 °C, has density about 1.34-1.36 g/cm³ and limited water solubility of roughly 19-25 g/L, while being soluble in alcohol, benzene, toluene, chloroform and DMF.
