Chlorobenzene (MCB), CAS 108-90-7, is also known as monochlorobenzene or phenyl chloride. It is used for industrial solvent and chemical-intermediate processes. Before requesting a quotation, confirm assay, water, acidity, distillation range, relevant impurities, packaging and intended process, and request current TDS, COA and SDS.

Industrial use and procurement boundary
1. Used as an industrial aromatic solvent and chemical intermediate; confirm the intended process and impurity profile.
2. Downstream synthesis can include selected aromatic chemicals; suitability depends on assay, water, acidity, distillation range and specific impurities.
3. Analytical-reference or other tightly controlled uses require a separate grade-specific specification; industrial supply wording does not establish reagent grade.
4. Before RFQ, define assay, water, acidity, distillation range, target process, packaging, quantity and destination.
FAQ - Technical & Supply Chain
-
Q:
Are Chlorobenzene and Monochlorobenzene (MCB) the same chemical?
A: Yes. Chlorobenzene and monochlorobenzene identify the same compound, CAS 108-90-7. They should not be treated as names for dichlorobenzene isomers or benzyl chloride. State the CAS number and the intended industrial grade in the purchase specification. -
Q:
Which release specifications matter for industrial Chlorobenzene?
A: Agree assay by gas chromatography, water, color, acidity or neutralization value, nonvolatile residue and limits for dichlorobenzene, benzene and other aromatic impurities. The test method and sampling basis matter because a nominal purity without an impurity profile is not sufficient for process approval.
