Monograph Number: 9006 Title: Sulfamic Acid CAS Registry Number: 5329-14-6 Molecular Formula: H3NO3S Molecular Weight: 97.09. Line Formula: H2NSO3H Properties: Orthorhombic crystals. d 2.15. mp ~205?(dec). Stable when dry but in soln it slowly hydrolyzes forming ammonium bisulfate. Sol in 6.5 parts water at 0? in about 2 parts water at 80? Sulfuric acid decreases its soly in water. It is sparingly sol in alcohol, methanol; slightly sol in acetone. Insol in ether. Freely sol in nitrogenous bases, e.g., liq ammonia, also in nitrogen contg organic solvents, e.g., pyridine, formamide, dimethylformamide. A strong acid; pH of a 1% soln at 25?1.18. Can be titrated with bases by means of indicators showing color change between pH 4.5 to 9. MLD orally in rats: 1.6 g/kg (Ambrose). Melting point: mp ~205?(dec) Density: d 2.15 Toxicity data: MLD orally in rats: 1.6 g/kg (Ambrose) CAUTION: Moderately irritating to skin, mucous membranes. 號碼是要寫哪個?5329-14-6還是9006? 藥品要寫中文還是英文@@? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 202.132.242.44
