Frequently asked questions
What is monochloroacetic acid (MCA) and what is it used for?
MCA (monochloroacetic acid, CAS 79-11-8) is a high-purity chemical intermediate supplied as white flakes. It is used primarily in carboxymethyl cellulose (CMC) production, and also in agrochemicals and herbicides (2,4-D, glyphosate), thioglycolic acid, betaine-type surfactants, and dye and pharmaceutical intermediates.
Is MCA the same as chloroacetic acid?
Yes. MCA is the abbreviation for monochloroacetic acid, which is the same substance as chloroacetic acid; both refer to CAS 79-11-8 with the formula C2H3ClO2. In supplier documents it may appear as monochloroacetic acid, chloroacetic acid or MCA.
How is MCA stored and transported?
MCA is stored in a cool, dry and well-ventilated area, kept away from moisture. Because it is corrosive, it is stored separately from food and oxidizers. Its shelf life is 12 months, and it can be transported by road and sea under UN 1751.
What is the typical purity of MCA?
MCA is supplied at a minimum purity of 99.0%. Typical impurity limits are dichloroacetic acid (DCA) max 0.5%, acetic acid max 0.3%, moisture max 0.5% and iron (Fe) max 10 mg/kg. The full specification and a certificate of analysis (CoA) are provided by KORKİMYA on request.
