(-)-Camphor

white crystals
L-camphor appears as colorless or white crystals. Fragrant and penetrating odor. Slightly bitter and cooling taste. Odor index at 68° F: 40. Flash point 149°F. Burns with a bright, smoky flame. Sublimes appreciably at room temperature and pressure; 14% sublimes within 60 minutes at 176°F and 12 mm Hg. (NTP, 1992)

It is an enantiomer of a (R)-camphor.|(S)-camphor, or L(-)-Camphor, is a stereoisomer of [DB01744], a bicyclic monoterpene known to potentiate both heat and cold sensations. (S)-camphor is not the naturally-occurring stereoisomer but displays similar TRPV channel affinity and current inhibition. [DB01744] is isolated from the wood of the camphor laurel tree, Cinnamomum camphora, and had a long history of medicinal use. It has been used as a nasal decongestant and cough suppressant, and has been topically applied due to its antipruritic, analgesic, and counterirritant properties. Camphor is a major active ingredient in over-the-counter balms and liniments supplied as topical analgesics by causing sensitization to heat and coolness to relieve minor muscle and joint pain.
