| Storage Class | 3 - Flammable liquids |
| Hazard Classifications | Acute Tox. 3 Oral Flam. Liq. 2 Skin Corr. 1B |
| Chemical Properties | Light yellow liquid |
| Uses | Propargyl chloride was used to study emission spectra of dissociating propargyl chloride upon photoexcitation at 199 nm. It was used in the synthesis of novel tetraaryl analog of bisphenol A and triaryl analog of bisphenol A propargyl resins. |
| Uses | Intermediate in organic synthesis. |
| General Description | Propargyl chloride is an efficient propargylating agent. It generates propargyl radicals by the pulsed laser photolysis. |
| Hazard | Flammable, moderate fire risk. |
| Purification Methods | Purify the chloride by fractional distillation at atmospheric pressure. Note that a possible impurity is propargyl alcohol which has has b 114-115o/~760mm (see above). [Henry Chem Ber 8 398 1875.] HIGHLY TOXIC and FLAMMABLE.[Beilstein 1 IV 960.] |
