Potassium Ferricyanide 13746-66-2— the small red crystal that wears many hats

Forget one-trick ponies. This orange-red crystal is the ultimate multi-tool — equally at home in a white-coat lab, a Hollywood film lab, or a roaring electro-plating hall. One formula, K₃[Fe(CN)₆], endless headlines.

1. Titration Titan
Delivers crisp, one-electron stoichiometry — hydrazine, ascorbate, Cu⁺, you name it. No overtitration, no back-tracking, just a razor-sharp colour flip and that famous green fluorescence under UV — perfect for photochemistry demos and Tik-Tok reels.

2. Photography's Time Machine
Still the gold-standard bleach for cinema colour negatives and cyanotype toning. It sweeps out residual silver, boosts contrast and leaves archival highlights that last a century — the reason classic prints look classic.

3. Factory Floor Powerhouse
Bright-brass electro-plating? Throw it in — mirror finish, no pits.
Molybdenum flotation? Add a pinch — recovery rates jump.
Aniline-black dyeing? One shot — blacks turn jet-black in half the time.
One salt, three industries, zero fuss.

4. Green & Travel-Ready
Low-toxicity solid, UN 3077 Class 9 PG III — no explosive licence, no special escort. Pack it, pallet it, air-freight or sea-freight on the next available carrier.

From titration flask to Hollywood studio, from plating bath to flotation cell, let this ruby crystal power your next breakthrough. Stock is stacked, ships are sailing—grab your ruby crystals and let the next reaction shine!
