Which Benzyl Mercaptan specifications should be agreed before ordering?

Specify GC assay, color, water and limits for dibenzyl disulfide, residual benzyl halide or benzyl alcohol. These controls help distinguish a fresh thiol-rich batch from oxidized material.

How is Benzyl Mercaptan packaged to control odor and oxidation?

Use an odor-tight compatible package with minimal air exposure. Package size, closure and transfer arrangement should support closed handling and comply with the shipment classification for the destination.

Can a Benzyl Mercaptan sample be supplied for route evaluation?

A sample can be discussed after specification and destination review. Test conversion, disulfide formation, work-up, odor control and downstream sulfur impurities under the intended conditions.

Why should dibenzyl disulfide be controlled separately from Benzyl Mercaptan assay?

Benzyl Mercaptan can oxidize to dibenzyl disulfide during storage and handling. A broad total-organics result may not reveal that conversion, so use a selective chromatographic profile and a thiol-related test when reaction performance depends on active mercaptan.

Benzyl Mercaptan CAS 100-53-8

Benzyl Mercaptan , CAS 100-53-8 and EC 202-862-5 , is the aromatic thiol phenylmethanethiol with molecular formula C7H8S and molecular weight 124.21 g/mol. It is strongly odorous and can oxidize to dibenzyl disulfide, making odor containment, assay, disulfide content, water, color and storage history important. It is supplied for controlled sulfur chemistry rather than open handling or unsupported end-use claims.

CAS: 100-53-8
Synonyms: Benzyl Mercaptan, Benzyl Thiol, Phenylmethanethiol, α-Toluenethiol, alpha-Toluenethiol
Einecs: 202-862-5
Molecular Formula: C₇H₈S
Grade: Confirm identity, assay method, water or residual solvents, product-specific impurities and physical form against the current COA; no end-use grade is assumed.
Package: State required quantity and destination; confirm the approved container or cylinder, inerting or stabilizer needs, closure or valve, fill quantity, temperature controls and dangerous-goods requirements against the SDS.

Identity and physicochemical profile

Item	Technical guidance
Product identity	Benzyl mercaptan; phenylmethanethiol
CAS / EC	100-53-8 / 202-862-5
Formula / molecular weight	C₇H₈S / 124.21 g/mol
Chemical character	Reactive, strongly odorous thiol susceptible to oxidation to dibenzyl disulfide
Key purchase controls	Identity, GC assay, dibenzyl disulfide, residual benzyl halide or alcohol, water, color, acidity and package integrity

Applications and grade selection

Benzyl Mercaptan may be evaluated in thioether formation, sulfur-functional intermediate synthesis, oxidation studies and other controlled organosulfur reactions. The buyer should qualify nucleophilic reactivity, oxidation state and impurity carryover in the intended route.

Define assay and individual limits for dibenzyl disulfide and route-derived benzyl impurities.
Plan closed sampling, odor control, compatible packaging and headspace management.
Compare conversion, selectivity and downstream odor or sulfur impurity removal at small scale.

Storage and handling

Keep sealed in odor-tight compatible packaging away from oxidizers, heat and ignition sources under the current SDS. Minimize air exposure and use a controlled procedure for sampling, resealing and spill management.

Safety, documentation and procurement

Use closed transfer, effective local exhaust and suitable personal protection. Procurement should define assay, disulfide limit, quantity, packaging, destination, odor controls and dangerous-goods requirements.
