FAQS on 95-45-4
Q: What is the CAS number 95-45-4 associated with?
A: CAS 95-45-4 corresponds to Ethylenediaminetetraacetic acid (EDTA), a chelating agent widely used in biochemistry and industrial applications. It binds metal ions to stabilize or remove them from solutions. Proper handling is required due to its potential environmental impact.
Q: How is Methyl Blue different from Phenolphthalein?
A: Methyl Blue (CAS 28983-56-4) is a biological stain and pH indicator, while Phenolphthalein (CAS 77-09-8) is a colorless pH indicator turning pink in basic solutions. Their applications and chemical structures differ significantly.
Q: What is the use of CAS 60-00-4 in laboratories?
A: CAS 60-00-4 identifies Ethylenediaminetetraacetic acid (EDTA), commonly used to sequester metal ions in buffer solutions. It prevents metal interference in experiments and is critical in molecular biology and medicine.
Q: Is Methyl Blue (CAS 28983-56-4) toxic?
A: Yes, Methyl Blue may cause eye/skin irritation and environmental toxicity. Always follow safety protocols, including wearing PPE and proper disposal methods, when handling this compound.
Q: Why is Phenolphthalein (CAS 77-09-8) used in titrations?
A: Phenolphthalein acts as a pH indicator, turning from colorless to bright pink in basic solutions (pH 8.2–10). Its clear visual transition makes it ideal for acid-base titration endpoint detection.
