FAQ - Technical & Supply Chain
-
Q:
Are 2-Methyl-2-butanol, tert-Amyl Alcohol and TAA the same substance?
A: Yes. These names commonly identify CAS 75-85-4, formula C₅H₁₂O. They should not be confused with 2-Methyl-1-butanol, 3-Methyl-2-butanol or mixed amyl alcohol. Use the complete name and CAS number because the abbreviation TAA can refer to other chemicals in different industries. -
Q:
Which specifications should be agreed for tert-Amyl Alcohol?
A: Define GC assay, water, acidity, color, density or refractive index, distillation range and relevant C5 alcohol or hydrocarbon impurities. Confirm whether a stabilizer is present and how it is reported. Review the batch COA and chromatogram against the intended solvent, synthesis or peroxide-process requirements. -
Q:
What should be confirmed for bulk 2-Methyl-2-butanol delivery?
A: Agree tanker, isotank, drum or IBC format, compatible seals, loading date, storage-temperature range and any inert-gas requirement. Its melting point is close enough to common winter conditions that warming or cold-weather handling may need planning. Approve the flammable-liquid controls, current SDS, grounding and closed-transfer connection before unloading.
