Test material
- Reference substance name:
- NMSBA
- IUPAC Name:
- NMSBA
- Reference substance name:
- 4-methanesulfonyl-2-nitrobenzoic acid
- EC Number:
- 601-017-1
- Cas Number:
- 110964-79-9
- Molecular formula:
- C8 H7 N1 O6 S1
- IUPAC Name:
- 4-methanesulfonyl-2-nitrobenzoic acid
- Details on test material:
- Study performed on Commercial Batch n°30014009 which relates to NMSBA crude containing 15% water but in line with substance identity as described in Section 1.2; Due to the sticky behaviour, before analysis, the crude wet product has to be dried in oven at 120°C during 48 hours.
