Diamond Hazard Value Description
2
2 0
HEALTH   2 Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury (e.g. diethyl ether, ammonium phosphate, iodine)
FIRE  2 Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur)
REACT   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

2-Methylpyrazine Chemical Properties,Uses,Production

Chemical Properties

clear colorless to slightly yellow liquid

Safety Profile

Moderately toxic by ingestion and intraperitoneal routes. Mutation data reported. Flammable liquid when exposed to heat, sparks, or flame. Can react with oxidizing materials. To fight fire, use water spray, foam, dry chemical, CO2. When heated to decomposition it emits highly toxic fumes of NOx.

Purification Methods

Purify it via the picrate and distil the free base. The picrate has m133-134o(from EtOH). [Wiggins & Wise J Chem Soc 4780 1956, Beilstein 23 III/IV 911, 23/5 V 386.]
