A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Methylisothiazolinone (CAS 2682-20-4) is a nitrogen-sulfur heterocyclic isothiazolinone biocide. It is used as an antimicrobial preservative in paints, latex emulsions, adhesives, metalworking and cutting fluids, paper coatings, and cooling and process water.
Frequently Asked Questions
What products contain methylisothiazolinone?
Methylisothiazolinone (CAS 2682-20-4) is an isothiazolinone biocide used as an antimicrobial preservative in latex paints and emulsions, water-based adhesives, metalworking and cutting fluids, paper coatings, and cooling and process water. RawSource supplies it in bulk for industrial preservation and slime control.
What is methylisothiazolinone used for?
It is an in-can and in-process preservative that controls bacterial and fungal growth in water-based industrial systems – paints, adhesives, metalworking fluids, and cooling water. It is a nitrogen-sulfur heterocyclic isothiazolinone (formula C4H5NOS).
What is the difference between methylisothiazolinone and methylchloroisothiazolinone?
They are related isothiazolinone biocides often used together; methylchloroisothiazolinone (CMIT) carries a chlorine substituent, while methylisothiazolinone (MIT, CAS 2682-20-4) does not. Blends combine the two for broader-spectrum preservation; MIT is also supplied alone. Request technical data from RawSource for the grade you need.
What CAS number and HS code apply to methylisothiazolinone?
CAS 2682-20-4; HS code 2934.99 (heterocyclic compounds, other). The chemical family is Specialty Additives (isothiazolinone biocide).
What bulk packaging and documentation are available?
RawSource supplies methylisothiazolinone in drums, totes, and IBCs for industrial use, with a Certificate of Analysis and Safety Data Sheet per shipment. Request a bulk quote with your target volume and active concentration for current pricing and lead time.
