What does MIC stand for?
| Full form | Methyl Isocyanate |
|---|---|
| Category | Science & engineering |
| Type | Abbreviation |
The abbreviation MIC stands for Methyl Isocyanate in chemical records. The NIOSH Pocket Guide lists MIC as a synonym for the substance with CAS number 624-83-9 and formula CH₃NCO.
In a chemical index, the abbreviation, chemical name, formula and registry number describe different fields of the same reference entry. Keep their labels when copying them: 624-83-9 is the CAS number, not a concentration or a date. CH₃NCO is a chemical formula, not a measurement taken from a container. A source listing a synonym tells you how that source names its entry; it does not establish the contents of an unidentified sample. For example, a fictional catalogue card headed Methyl Isocyanate can retain MIC as its abbreviation and 624-83-9 as its stated CAS field. A separate unlabeled sample cannot be identified simply because that card is nearby. This guide helps readers recognize and transcribe the name in a reference record. Its exercise contains no chemical test, exposure calculation or handling procedure. If a document uses MIC beside a number, first identify the subject and the field label rather than assuming that a microbiology concentration or an audio label refers to this chemical.
Meaning in context
- Methyl Isocyanate
- The chemical name that NIOSH associates with the synonym MIC.
- CAS 624-83-9
- The registry-number field in the NIOSH reference entry.
- CH₃NCO
- The formula field, separate from a measured concentration.
Practical examples
Copy the right field
- Before
Invented index row: name Methyl Isocyanate; abbreviation MIC; CAS 624-83-9. Draft: The concentration is 624-83-9.
- After
The fictional index identifies Methyl Isocyanate (MIC), CAS 624-83-9.
The value belongs to the named identifier field. The row supplies no measured concentration.
Do not identify a sample by proximity
- Before
An invented folder contains an MIC reference card and a photograph of an unlabeled container. Draft: The photograph proves the container holds MIC.
- After
The folder contains an MIC reference card; the unlabeled container has not been identified by the supplied material.
A nearby reference is not an analysis or a reliable label for that object.
Original illustrative examples, not quotations or reports of actual events.

Methyl Isocyanate (MIC).
Transcribe an identifier
Keep CAS and formula labels beside their values.
CAS: 624-83-9; formula: CH₃NCO.
Describe an unknown sample
State the identification gap rather than filling it from a nearby term.
The supplied photograph does not identify the contents.
Keep the chemical name, formula and CAS number in their own fields; a reference entry does not identify an unknown sample.
