Methylene bis(thiocyanate) · MBT / MTC
Retained as a specialized option requiring verification, with historical industrial water uses. First resolve ambiguity in the abbreviation MBT, then check the current product label, closed metering and occupational exposure conditions.
Product uses
A specialized industrial-water candidate subject to current label restrictions.

Purchasing informationView parameter guidance ↓
- Chemical identity / CAS
- 6317-18-6Methylene bisthiocyanate ↗
- Physical form / Type
- Substance information describes a yellow to pale-orange solid or powder; commercial formulation forms require separate verification.
- Key purchasing comparisons
- Full English name and chemical identityCurrent uses and product documentsClosed metering and exposure control
- Packaging and delivery
- First confirm raw material or solvent-based formulation, retaining the full English name on packaging; then check container materials, closures and withdrawal methods.
Identity and physical form identify the product; specific concentration, grade, packaging and uses are governed by mutually confirmed formulated-product documents.
01 / Product and applications
Uses and product form
Chemical identity / Technical type
Here MBT means methylene bis(thiocyanate), not mercaptobenzothiazole used in corrosion inhibition or rubber applications.
Appearance and delivery form
Confirm the current supplied raw material or formulation's form, solvent and color against documents.
Identity note
MBT/MTC on this page means methylene bis(thiocyanate). Other industries also use MBT for mercaptobenzothiazole, so searches, contracts and SDS checks must include both the full English name and CAS.
02 / Specification selection
Key purchasing parameters
| Items to confirm | Relevance to purchasing and use |
|---|---|
| Full English name and chemical identity | Prevent purchasing the wrong MBT across industries. |
| Current uses and product documents | Historical EPA assessments do not replace current authorization. |
| Closed metering and exposure control | Occupational exposure requirements may determine site usability. |
Include parameters, test methods and acceptance checkpoints in purchasing requirements to compare specifications.
03 / Applications and limits
Applications and conditions of use
These are starting points for conditional verification. Specific product suitability still requires joint confirmation through product documents, operating conditions and destination requirements.
Additional checks before use
- Not automatically associated with drinking water, recreational water involving human exposure or live aquaculture.
- Historical uses cannot be presented as current ENVO approvals.
- Do not finalize selection before current product and facility verification.
04 / Common challenges

06 / Frequently asked questions
Purchasing FAQs
Why must MBT's full name be checked?
Different industries use the same abbreviation for different chemicals.
Do old EPA documents establish current usability?
No. They establish only historical assessment of the relevant approach.
Can it be recommended for all industrial water?
No. This page retains only a conditional screening entry for limited applications.

Names and searches
Purchasing MBT biocide: how can confusion with corrosion-related chemicals using the same abbreviation be avoided?
Three letters do not sufficiently identify a purchasing chemical. MBT can be ambiguous in water-treatment searches; confirm methylene bisthiocyanate through the full name, chemical identity and function.

Delivery preparation
Why confirm site receipt and metering conditions before an MBT product arrives?
Industrial biocide delivery involves more than stock availability and arrival date. Before purchasing MBT, clarify packaging, transfer connections, metering and staffing so the product can be received and used according to its requirements.

Sampling and acceptance
Sampling an MBT dispersion: why might taking only clear liquid at the bottle opening be unrepresentative?
Acceptance of dispersions and homogeneous solutions cannot follow identical assumptions. Explain sampling representativeness, sample condition and analytical method together to interpret MBT formulation batch results.
