There were two kinds of data for rat inhalation for 4 hours LC50 = 219ppm and 55ppm (ACGIH (2001)). And it was classified as Category 1 based on the lower value of 55ppm.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available

8 Specific target organ toxicity - Single exposure Category 1 (central nervous system, kidney), Category 3 (respiratory tract irritation) Danger
Warning
H370: Causes damage to organs (central nervous system, kidney)
H335: May cause respiratory irritation (respiratory tract irritation)
P307+P311: IF exposed: Call a POISON CENTER or doctor/physician.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P321: Specific treatment (see ... on this label).
P405: Store locked up.
P501: Dispose of contents/container to ...
P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P403+P233: Store in a well-ventilated place. Keep container tightly closed.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P271: Use only outdoors or in a well-ventilated area.
P312: Call a POISON CENTER or doctor/physician if you feel unwell.
There is many reports of the central-nerves condition in the humans in an accident (PATTY (5th, 2001), ACGIH (2001), IARC 39 (1986), DFGOTvol.6 (1994)), and the report of effect into the central-nerves condition and the kidney in rabbit (ACGIH (2001), IARC 39 (1986)), and in rat (PATTY (5th, 2001)). So it classified into Category 1 (central nervous systems, kidney) . And based on the accident reporting of respiratory irritation in human (PATTY (5th, 2001), IARC 39 (1986)), it is classified into category 3 (respiratory irritation).
9 Specific target organ toxicity - Repeated exposure Category 1 (kidney), Category 2 (central nervous system) Danger
Warning
H372: Cause damage to organs through prolonged or repeated exposure (kidney)
H373: May cause damage to organs through prolonged or repeated exposure (central nervous system)
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ...
Based on that effect to the kidney is acknowledged in rat inhalation study (ACGIH (2001), DFGOTvol.6 (1994), PATTY (5th, 2001), IARC 39 (1986)), it was classified as Category 1 (kidney). Moreover, based on that the central nervous systems effects is acknowledged in the oral examination of a rat (ACGIH (2001), DFGOTvol.6 (1994)), it was classified as Category 2 (central nervous systems).
