If you’re synthesizing advanced pharmaceuticals or next-gen pesticides, chances are you’ve crossed paths with pivaloylacetonitrile (CAS 59997-51-2). Marketed as Cyanopinacolone or systematically dubbed 1-Cyano-3,3-dimethylbutan-2-one, this crystalline specialist punches above its weight. Beyond its textbook specs – C₇H₁₁NO formula and 125.17 g/mol mass – it’s that clever fusion of nitrile reactivity and *sterically shielded ketone* that makes synthetic chemists reach for it repeatedly.

Why Its Physical Traits Matter

Picture a white-to-cream crystalline powder behaving rather finickily with water (it practically shrugs water off) yet playing nice with organic solvents. Key specs tell the story:
    Melts between 66–69°C with a flash point near 59.5°C – handle carefully
   Boils at 125–126°C(under reduced pressure: 22 mmHg)
   Density hovers around 1.0459 g/cm³
   Stores without fuss if you keep it sealed, dry, and shaded

That crystalline stubbornness? It’s why industrial teams trust it for controlled reactions and shelf-stable inventories.

Where This Molecule Shines

Pharmaceutical frontiers:Ever worked with 1,1-dimethyl-3-uracil derivatives? Cyanopinacolone is your gateway. But its resume stretches further:
   Agrochemical innovation:Builds backbone structures for cutting-edge crop shields
  Imaging tech:Raw material for niche photosensitizers in film applications
  Heterocyclic wizardry:Research teams leverage its dance between ketone and nitrile groups to spin novel functional materials

Here’s why chemists value it:That bulky *tert*-butyl group imposes delicious selectivity during condensations or cyclizations, while the nitrile acts like a chemical "and" connector – perfect for multi-step syntheses.

Real-World Chemical Impact

On production floors, Cyanopinacolone’s **steric hindrance** isn’t just academic; it’s what enables precise reaction pathways in fine chemical manufacturing. Meanwhile, lab benches worldwide exploit its duality to engineer everything from bioactive heterocycles to light-responsive compounds.

The Takeaway

Pivaloylacetonitrile (CAS 59997-51-2) isn’t just another bottle on the shelf. It’s a **versatility powerhouse** merging stability, reactivity, and synthetic flexibility – whether you’re crafting life-saving drugs, eco-friendly pesticides, or advanced photosensitive materials. Think of it as chemistry’s precision multitool.
