How does a "chemical for synthesis" compare with the same chemical(ACS grade)when used in analytical testing?

Chemicals are supplied in different grades,e.g. ACS,AR...etc.What do we mean when we say that the chemical is for synthesis?

We mean that the chemical in question is suitable to use for synthesis (making some other compound).
When I answered this question for you yesterday, I simply defined the word synthesis for you. I have never used a term "chemical for synthesis" to determine the purity of a chemical. Here is a site that gives the various grades and their definitions that I have used in my career.
However, here is an extended list by another vendor which may come closer to answering your question.
Note that your question today is not phrased the same as when you asked yesterday. Yesterday the emphasis, I thought, was on synthesis. Today, the emphasis appears to be on the use of these chemicals for analytical testing. As an analytical chemist I would not want to use them for analytical testing. I want to use primary standard grade, AR(ACS), Reagent Grade (ACS), or GR for my work.
