FAQ - Technical & Supply Chain
-
Q:
Are Sodium Methanethiolate and Sodium Thiomethoxide the same substance?
A: Yes. These names identify sodium methanethiolate, CAS 5188-07-8, often supplied as an aqueous solution. It is not methanethiol, sodium methoxide or a generic sulfide solution. State the full name, CAS number and concentration or form in every purchasing document. -
Q:
Which specifications matter for Sodium Methanethiolate solution?
A: Agree sodium methanethiolate concentration and method, pH or alkalinity, sodium hydroxide, sulfide or disulfide, methanol, water, color and insoluble matter. State whether the result is reported as active salt or equivalent sulfur. Compare the batch COA at the actual solution concentration before charging.
