Description of key information
Acute toxicity: oral
The acute toxicity study was predicted using OECD QSAR toolbox version 3.3 (2017); to evaluate the toxic effects of administration of N-[3-(diethylamino)ph enyl]acetamide (CAS No. 6375-46-8) in mouse by the oral route. 50% mortality was observed. The acute oral median lethal dose (LD50) of N-[3-(diethylamino) phenyl]acetamide in mouse was estimated to be 3306.05 mg/kg b.wt. Thus by considering the CLP criteria for acute toxicity rating for the chemicals, it infers that N-[3-(diethylamino)phenyl]acetamide (CAS No. 6375-46-8) does not exhibit acute toxicity via the oral route.

Additional information
Acute toxicity: oral
Various studies including predicted results from the validated model and experimental study has been investigated for acute oral toxicity to a greater or lesser extent for the test chemical N-[3-(diethylamino)ph enyl]acetamide (CAS No. 6375-46-8) along with its structurally similar read across substances disodium 4,4'-bis[[6-anilino-4-[(2-hydroxyethyl)methylamino]-1,3,5-triazin-2-yl]amino]stilbene-2,2'-disulphonate (CAS No. 13863-31-5) and disodium 4,4'-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]s tilbene-2, 2'-disulphonate (CAS No. 16090 -02 -1). The predicted data for target chemical N-[3-(diethylamino)phenyl]acetamide (CAS No. 6375-46-8) has been compared with experimental data (in vivo experiments in rodents i.e. most commonly in rats) for read across substance which are summarized as below:
The acute toxicity study was predicted using OECD QSAR toolbox version 3.3 (2017); to evaluate the toxic effects of administration of N-[3-(diethylamino)phenyl] acetamide (CAS No. 6375-46-8) in mouse by the oral route. 50% mortality was observed. Thus, the acute oral median lethal dose (LD50) of N-[3-(diethylamino) phenyl]acetamide in mouse was estimated to be 3306.05 mg/kg b.wt.
The above study is supported by the study based on the QSAR prediction done using the Danish (Q)SAR Database, in which the acute toxicity study was estimated to evaluate the toxic effects of administration of N-[3-(diethylamino)phenyl]acetamide (CAS No. 6375-46-8) in rat by the oral route. 50% mortality was observed. The acute oral median lethal dose (LD50) of N-[3-(diethylamino)phenyl]acetamide in rat was estimated to be 2800 mg/kg/day.
This is further supported by the experimental acute toxicity study done by Alan W. Burg et.al (C R C Critical Reviews in Environmental Control, 7:1, 91-120, 1977.) to evaluate the toxic effects of administration of Disodium 4,4'-bis[[6 -anilino-4-[(2-hydroxyethyl)methylamino]-1,3,5 -triazin-2-yl]amino]stilbene-2,2'-disulphonate (CAS No. 13863-31-5) in rat by the oral route. 50% mortality was observed. The acute oral median lethal dose (LD50) of Disodium 4,4'-bis[[6-anilino-4-[(2-hydroxyethyl)methylamino]-1,3,5-triazin-2-yl]amino] stilbene-2,2'-disulphonate in rat was observed to be >10000 mg/kg b.wt.
Moreover, the acute toxicity study conducted by Alan W. Burg et.al (C R C Critical Reviews in Environmental Control, 7:1, 91-120, 1977.) was to evaluate the toxic effects of administration of Disodium 4,4'-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino] stilb ene-2,2'-disulphonate (CAS No. 16090 -02-) in rat by the oral route. 50% mortality was observed. The acute oral median lethal dose (LD50) of Disodium 4,4'-bis[(4-anilino-6-morpholino-1,3,5- triazin-2-yl) amino]stilbene-2,2'-disulphonate in rat was observed to be >8000 mg/kg b.wt.
So, based on the above mentioned studies for target substance N-[3-(diethylamino)phenyl]acetamide (CAS No. 6375-46-8) and to its read across substance, the median lethal dose (LD50) value was found to be in the range of 2800 mg/kg bw to >10000 mg/kg b.wt. Thus, by comparing these studies with the criteria of CLP regulation, it infers that the test substance N-[3-(diethylamino)ph enyl]acetamide (CAS No. 6375-46-8) does not classify as an acute oral toxicant.
Justification for classification or non-classification
Based on the above mentioned studies for target substance N-[3-(diethylamino)ph enyl]acetamide (CAS No. 6375-46-8) and to its read across substance, it can be found that LD50 value is greater than 2000 mg/kg b.wt. Thus, by comparing these studies with the criteria of CLP regulation, it infers that the test substance N-[3-(diethylamino)phenyl]acetamide (CAS No. 6375-46-8) does not classify as an acute oral toxicant.
