Command words are magic which alchemical items are not. This, I believe, is invalid.

To make an item using Craft (alchemy), you must have alchemical equipment and be a spellcaster. If you are working in a city, you can buy what you need as part of the raw materials cost to make the item, but alchemical equipment is difficult or impossible to come by in some places. Purchasing and maintaining an alchemist’s lab grants a +2 circumstance bonus on Craft (alchemy) checks because you have the perfect tools for the job, but it does not affect the cost of any items made using the skill.
