Potassium bromide≥99.0%Linear Formula: KBrCAS Number: 7758-02-3Molecular Weight: 119.00EC Number: 231-830-3MDL number: MFCD00011358 ApplicationUsed as a source of bromide ions to obtain silver bromide, which is used for the manufacture of photographic and film films.Attachment for an IR spectrophotometer for studying the spectra of liquid substances in potassium bromide tabletsIt is used in photographic developers as an anti-fogging agent. Compared to other anti-valents, it practically does not raise the image contrast.To study the IR spectra of liquid substances, the technology of placing a substance between plates of potassium bromide (the so-called "tablet") is often used. Potassium bromide does not absorb infrared radiation in a sufficiently wide range of wavelengths (from 0.25 μm to 25 μm), which makes it possible to use it for these purposes.
