Chemische Eigenschaften
p-Cresidine is a white crystalline solid.
Verwenden
p-Cresidine is a reagent used in the preparation of enaminones acting as anticonvulsants. Also used in the preparation of crescent oligoamides. Dyes and metabolites, Environmental Testing.
Verwenden
2-Methoxy-5-methylaniline was used in the synthesis of 4-(4-Amino-5-methoxy-2-methylphenylazo)-5-hydroxy-naphthalene-2,7-disulfonic acid. 2-Methoxy-5-methylaniline was used to analyse the application of polymeric ionic liquids as selective solid-phase microextraction sorbent coatings for the analysis of genotoxic impurities and structurally alerting compounds such as alkyl halides and aromatics. 2-Methoxy-5-methylaniline was used in a study to develop a sensitive analytical method for the determination of aromatic amines found in commercial hair dyes using high liquid chromatography coupled to an electrochemical detector by using the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide in the mobile phase.

Erste Hilfe
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.
Note to physician: Treat for methemoglobinemia.Spectrophotometry may be required for precise determination of levels of methemoglobinemia in urine.
Carcinogenicity
p-Cresidine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
Lager
Color Code—Blue (potential carcinogen): HealthHazard/Poison: Store in a secure poison location. Prior toworking with this chemical you should be trained on itsproper handling and storage. Before entering confined spacewhere this chemical may be present, check to make surethat an explosive concentration does not exist. Store intightly closed containers in a cool, well-ventilated areaaway from oxidizers. Store in a refrigerator under an inertatmosphere for prolonged storage. A regulated, marked areashould be established where this chemical is handled, used,or stored in compliance with OSHA Standard 1910.1045.
