Color and Odor: Off-white, odorless solid.
CAS No. 1305-78-8
 SPECIAL HAZARD ALERT: Avoiding moisture contact is important in storing this substance. We suggest high humidity exposure may have resulted in the generation of sufficient heat to crack or break the glass bottle. Flinn’s product is not packaged in glass; however, that does not negate the need to keep this substance dry. We package this substance in a plastic bottle. The bottle is in a plastic bag and contained within the bag is a desiccant to reduce or absorb moisture. Continue to store this material under similar conditions. Buy only small quantities of this substance.
