Without looking up that particular refrigerant I can tell you that it falls into one of two categories, it is a hydrocarbon (flammable) or it is a blend.
If it is a hydrocarbon it is illegal for use in Mobile a/c systems in 18 states. If it is a blend then when a leak occurs you have to recover, evacuate and totally recharge. Regardless of which category it falls into, to use it legally you have to install the correct fittings and label the system. Most people violate this law which leads to it being recovered by an auto a/c shop which results in the contamination of all refrigerant in that recovery tank. This means that this junk contaminates a lot of refrigerant costing the independent shops lots of money. Them losing money means that they have to pass on this expense to their innocent customers or go out of business. In my experience there is never something for nothing in life. Either use R12 or convert to R134a and you will be in good shape. When you see these alternative refrigerants you should immediately think "Snake Oil." Have a great day,

Here's what the EPA has to say about altenative refrigerants.. Best I can figure.. The reason why these alternative refrigerants are not used often are.. 1 Not approved by auto manufacturer( someone paying someone else) 2 Illegal to release into the air, difficult to find someone to recover it. (probably the biggest reason) 3 That's all I have so far.. There's plenty of r-12 still available, and it really doesn't cost that much more.. A little more than double.. But, since I bought a Benz, I'm getting used to paying $60 for a $20 part

Does sound miraculous.
If I remember right, that one is like %80 r-134a. With r-12 now around $25 per pound, all of these alternative refrigerants are looking fairly silly. Now, compare $50-60 worth of refrigerant to the cost of a new compressor, or any other AC component, for that matter... Freezone is around $17 per pound. How much are you saving? %80 r-134a. Nice profit margin! How much does that 142b cost them? Not only that, this one still requires a 609 license to purchase! The more you dig into the vast array of miraculous alternatives, the less appealing they become.
