I would recommend that you do some research regarding the possession of "research only" chemicals by a non scientific entity (including an authentic researcher).
Many chemicals found in a standard lab are for professional research use only and you must be a research entity (lab, university, etc.) to purchase/possess them (based on my experiences in lab). It's similar to trinitrotolune (TNT).....it's a common chemcial but you just can't go out and buy it at Home Depot to make bombs. It's a controlled chemical for professional use only (with a license).
Legality varies by state and/or country.
