DOCUMENT NUMBER_ SSS-003 CATEGORY DETAIL EC Number 215-175-0 CAS Number 1309-64-4 Name Subclass 1 Antimony Trioxide (ATO) Structural Formula CHEMICAL IDENTITY PROPERTY DETAIL Physical State Solid Form Powder Color White Odor Odorless Melting Point 656°C Boiling Point 1425°C Bulk Density 5.20 g/cm3 Water Solubility Slightly Soluble PHYSICAL/ CHEMICAL PROPERTIES DOCUMENT NUMBER_ SSS-003 HEALTH EFFECTS HUMAN HEALTH SAFETY ASSESSMENT Consumer It is very unlikely that consumers would be exposed to ATO in its concentrated form because it is only sold for industrial use to make polymers and other products and is not sold directly to consumers.

See Annex C for examples of information that may be considered Inside Information. Pre-arranged Trading Plans: An SEC rule, Rule 10b5-1(c), provides a defense from insider trading liability if trades occur pursuant to a pre-arranged “trading plan” that meets specified conditions. Please note that, in addition to the requirements of a trading plan described above, there are a number of additional procedural conditions to Rule 10b5-1(c) that must be satisfied before you can rely on a trading plan as an affirmative defense against an insider trading charge.
