An interesting issue was recently brought to our attention regarding Oxandrolone. A Customer had received a batch and found it to be melting at 205-207c rather than the stated melting point of Oxandrolone which is 235-237c.
After concerns that there was an issue over mislabelling we have finally come to an interesting discovery regarding this compound.
Please see the chemical details below:-

Bolded above is the Melting Point of the compound and also the Flash Point of the compound. What are they?
The Melting Point is self explanatory for most, it is just the temperature the compound turns from a Solid to a Liquid.
This is the definition of the Flash Point on Wikipedia:
"The flash point of a volatile material is the lowest temperature at which it can vaporize.."
Very, very few Steroids have a "Flash Point" but what is interesting in this instance is that Oxandrolone's Flash Point is LOWER than is Melting Point i.e it vaporizes BEFORE it melts!
What does this mean?
It means that if you try to do a melting point test on this compound, unless completed in a special environment (free from Oxygen?) - it will NOT melt at 235c.
What is more interesting is how simply taking an average of the Flash Point and Melting Point produces the exact temperature the compound DOES melt at.
(235c + 179c) / 2 = 207c
Hope you've all found this interesting!
