Low‑color program for appearance‑sensitive work. We can supply tighter GC/volatiles/color on request; share your method and limits for alignment.
| Framework | Status | Notes |
|---|---|---|
| Intended use | Industrial / R&D | not for food, cosmetic, or fragrance use |
| REACH | Registered/Notified (supplier‑specific) | confirm tonnage and uses for coverage |
| GHS | See SDS | classification & labeling per latest SDS |
| RoHS (EEE) | Not targeted | not marketed for EEE use claims |
Compliance is application‑specific. Provide your regulatory basis (REACH, SVHC checks, OEM lists) and we’ll match paperwork and grade.
| Item | Status | Notes |
|---|---|---|
| DG classification | Typically non‑DG liquid | verify per route/carrier |
| Flash / ignition | combustible | keep away from heat/sparks; see SDS |
| Handling | avoid inhalation/skin contact | use closed transfers; LEV as needed |
| Incompatibilities | strong oxidizers | store away accordingly |
| PPE | gloves, goggles, protective clothing | industrial hygiene per SDS |
| Spills/Disposal | absorb with inert material | dispose per local regulations |
Store cool and dry in sealed containers. Record GC purity, water, and color on receipt; maintain batch traceability. Always consult the SDS.

• Intermediate for pharmaceuticals and specialty
materials.
• Solvent/medium in synthesis; aryl‑ketone building block. • General organic synthesis and R&D. |
• 1 kg amber glass bottles (sample/bench).
• 25 kg drums; 200 kg drums. • Custom packs and nitrogen blanketing on request. |
• Store in cool, ventilated area away from oxidizers.
• Keep container tightly closed; use clean pumps/hoses. • Minimize headspace to limit oxidation/odor. |
Specs are representative; shipped material conforms to the lot
COA. For tight programs, share your GC assay method, impurity
limits, water/color targets, and any documentation needs so we can
quote the correct grade.
