FAQ - Technical & Supply Chain
-
Q:
Are 2-Chloroaniline and o-Chloroaniline the same substance?
A: Yes. Both names identify the ortho isomer, CAS 95-51-2, formula C₆H₆ClN. They are not interchangeable with 3-Chloroaniline or 4-Chloroaniline. Confirm the position-specific name, CAS number and chromatographic identity because a generic chloroaniline description does not establish the required isomer. -
Q:
Which specifications matter when purchasing 2-Chloroaniline?
A: Agree GC assay, 3- and 4-Chloroaniline limits, residual Aniline and Dichloroanilines, water, color, density or refractive index and distillation range where applicable. State the impurity reporting threshold and method. Review the batch chromatogram or COA rather than relying on total purity without isomer detail. -
Q:
What should be confirmed for bulk o-Chloroaniline handling?
A: Specify a compatible closed drum, IBC or tank system, seal materials, transfer connection, loading temperature and protection from contamination. The receiving site should approve the current SDS, toxic-liquid transport classification, ventilation, exposure controls and spill containment before dispatch. Confirm destination-market inventory or restriction documents where required.
